Primitives in AngelScript have direct matches in C++.
| AngelScript | C++ | Size (bits) |
| void | void | 0 |
| int8 | signed char | 8 |
| int16 | signed short | 16 |
| int | signed long (*) | 32 |
| int64 | signed long long | 64 |
| uint8 | unsigned char | 8 |
| uint16 | unsigned short | 16 |
| uint | unsigned long (*) | 32 |
| uint64 | unsigned long long | 64 |
| float | float | 32 |
| double | double | 64 |
| bool | bool | 8 (**) |
*) If the target CPU is 32 bit, the C++ type long is 32 bit, but on 64 bit CPUs it is commonly 64 bit, but in AngelScript an int is always 32 bits.
**) On 32 bit PowerPC platforms the bool type commonly have the size of 32 bit, when compiled on such platforms AngelScript also uses 32 bits for the bool type
The AngelScript arrays are not directly matched by C++ arrays. The arrays are stored in an special object. Thus you can normally not directly exchange a script with a C++ function expecting a C++ array, or vice versa. Nor can the application register C++ arrays as properties and expect AngelScript to be able to understand them.
It is however possible to override AngelScript's built-in array objects with application specified objects, on a per array type basis.
The AngelScript object handles are reference counted pointers to objects. This means that for object handles to work, the object must have some way of counting references, for example an AddRef/Release method pair.
When AngelScript passes an object handle by value to a function it increases the reference count to count for the argument instance, thus the function is responsible for releasing the reference once it is finished with it. In the same manner AngelScript expects any handle returned from a function to already have the reference accounted for.
However, when registering functions/methods with AngelScript the application can tell the library that it should automatically take care of releasing the handle references once a function return, likewise for returned handles. This is done by adding a + sign to the @ type modifier. When doing this an object handle can be safely passed to a C++ function that expects a normal pointer, but don't release it afterwards.
Because AngelScript needs to guarantee validity of pointers at all times, it doesn't always pass references to the true object to the function parameter. Instead it creates a copy of the object, whose reference is passed to the function, and if the reference is marked to return a value, the clone is copied back to the original object (if it still exists) once the function returns.
Because of this, AngelScript's parameter references are mostly compatible with C++ references, or pointers, except that the address normally shouldn't be stored for later use, since the object may be destroyed once the function returns.
If it is necessary to store the address of the object, then object handles should be used instead.
| Reference | Description |
| &in | A copy of the value is always taken and the reference to the copy is passed to the function. For script functions this is not useful, but it is maintained for compatibility with application registered functions. |
| const &in | If the life time of the value can be guaranteed to be valid during the execution of the function, the reference to the true object is passed to the function, otherwise a copy is made. |
| &out | A reference to an unitialized value is passed to the function. When the function returns the value is copied to the true reference. The argument expression is evaluated only after the function call. This is the best way to have functions return multiple values. |
| const &out | Useless as the function wouldn't be able to modify the value. |
| &inout | The true reference is always passed to the function. If the life time of the value cannot be guaranteed, a compile time error is generated and the script writer will have to copy the value to a local variable first. Objects that support object handles are best suitable for this type as they can always be guaranteed. |
| const &inout | The reference cannot be changed by the function. |
If the application wants parameter references that work like they do in C++, then the engine property asEP_ALLOW_UNSAFE_REFERENCES can be set. When this is done, the parameter references can be declared without the in
, out
, or inout
. The parameter references declared without any of the keywords will always pass the address to the original value, and will not have any restrictions to the expressions that can be used. The parameter references with the in
and out
keywords will still work like before, but the references with the inout
keyword will have the restrictions removed so that they work just like normal C++ references.
The application writer and script writer has to be aware that it is possible to write scripts that access invalid references when the library is compiled in this mode, just like it is possible to do so in C++.


Supporting Frameworks
The following tutorial shows how to support a custom framework type for a project and make this framework type embedded in a project wizard as a UI component.n The examples in this tutorial rely heavily on the framework_basics code sample.
1. Creating a new framework
In oder to make a custom framework available and configurable for a project the FrameworkTypeEx
class needs to be extended, in this example to make the DemoFramework class.
public class DemoFramework extends FrameworkTypeEx {
}
2. Registering framework
The newly created framework class should be registered as an extension point by adding com.intellij.framework.type
extension in
plugin.xml
configuration file:
<extensions defaultExtensionNs="com.intellij">
<framework.type implementation="org.intellij.sdk.framework.DemoFramework"/>
</extensions>
3. Setting up mandatory attributes
The framework component should have a unique name passed as a string literal to the constructor. It is best if this is the FQN name of the class:
public class DemoFramework extends FrameworkTypeEx {
public static final String FRAMEWORK_ID = "org.intellij.sdk.framework.DemoFramework";
protected DemoFramework() {
super(FRAMEWORK_ID);
}
}
The Presentable name and icon define the appearance of visual components related to the framework:
public class DemoFramework extends FrameworkTypeEx {
@NotNull
@Override
public String getPresentableName() {
return "SDK Demo Framework";
}
@NotNull
@Override
public Icon getIcon() {
return SdkIcons.Sdk_default_icon;
}
}
4. Creating provider for enabling framework support
To make the framework set up available while executing the steps to create a project, the
DemoFramework.createProvider()
method must be implemented to return an object of type FrameworkSupportInModuleConfigurable
, which adds the framework to a module.
In this example the framework is added to any ModuleType
without checking, which is usually not the case.
@NotNull
@Override
public FrameworkSupportInModuleProvider createProvider() {
return new FrameworkSupportInModuleProvider() {
@NotNull
@Override
public FrameworkTypeEx getFrameworkType() {
return DemoFramework.this;
}
@NotNull
@Override
public FrameworkSupportInModuleConfigurable createConfigurable(@NotNull FrameworkSupportModel model) {
return new FrameworkSupportInModuleConfigurable() {
@Nullable
@Override
public JComponent createComponent() {
return new JCheckBox("SDK Extra Option");
}
@Override
public void addSupport(@NotNull Module module, @NotNull ModifiableRootModel model, @NotNull ModifiableModelsProvider provider) {
// This is the place to set up a library, generate a specific file, etc
// and actually add framework support to a module.
}
};
}
@Override
public boolean isEnabledForModuleType(@NotNull ModuleType type) {
return true;
}
};
}
After compiling and running the code sample above an extra option for configuring the newly created Demo custom framework should be available in the Project Wizard:

This is a variation on Audio Demo 9, which does not use an iframe.
For additional demos see the Index of Able Player Examples.
Ordinarily, when users are interacting with form fields, their keystrokes should not be handled by the player. However, in some contexts (e.g., in a transcription application), users may want to control the player from within a textarea field. To enable this functionality, add data-steno-mode to the <audio> or <video> element. Note: Modifier keys for keyboard shortcuts can be configured within Preferences > Keyboard.
In this variation, the transcription form is contained within an iframe. To make this work, the <iframe> element must have a unique id. Then add data-steno-iframe-id to the <audio> or <video> element, with a value that matches the id of the iframe.

Search operation launched after reports of plane crash off North Wales coast
HM Coastguard is co-ordinating a search in the Puffin Island area near Anglesey after the light aircraft disappeared from radar at around midday.
A rescue operation has been launched after reports of an aircraft crash off the North Wales coast.
HM Coastguard said it was co-ordinating a search in the Puffin Island area near Anglesey after the light aircraft disappeared from radar at around midday on Monday.
Police are assisting the coastguard with the search, which includes a helicopter and RNLI lifeboats, but it is not yet known how many people were on board the plane.
A spokesman for the coastguard said: “HM Coastguard is currently co-ordinating a search and rescue in the Puffin Island area of North Wales following a report at 12.47pm today that an aircraft had disappeared from radar contact.
“The search and rescue helicopter from Caernarfon has been sent as well as Coastguard rescue teams from Penmon and Bangor and a senior Coastguard operations officer.
“The RNLI lifeboats from Beaumaris, Moelfre and Llandudno and North Wales Police have been sent.
“It has not been confirmed how many people were on board the aircraft.
“The incident is ongoing and we have no further information at this time.”
A spokesman for North Wales Police said: “We received a call at 12.59pm today reporting a possible crash involving a light aircraft in the Penmon area.
“Officers are currently assisting HM Coastguard and our inquiries are ongoing.”
The Air Accidents Investigation Branch said in a statement: “The AAIB has sent a team to investigate an accident involving a light aircraft that occurred near Beaumaris, Gwynedd, Wales.”

Compute the islands of awake bodies.
An island is an isolated group of rigid bodies that have constraints (joints or contacts) between each other.
This method computes the islands at each time step as follows: For each awake rigid body, we run a Depth First Search (DFS) through the constraint graph of that body (graph where nodes are the bodies and where the edges are the constraints between the bodies) to find all the bodies that are connected with it (the bodies that share joints or contacts with it). Then, we create an island with this group of connected bodies.

TCL introduces a 10.8 inch, 240 Hz display for gaming tablets
by Brad LinderThere are a handful of laptops with 240 Hz displays, and even a few portable monitors. But you know what we haven’t seen yet? A tablet with a screen that refreshes 240 times per second.
Those could soon be a reality though.
According to a post to Chinese social media network Weibo, it looks like TCL is showing off a 10.8 inch, 240 Hz tablet display.
The screen has a resolution of 2560 x 1600 pixels which means there are 280 pixels per inch. It also supports up to 500 nits of brightness, and… it features a punch hole in one corner, allowing tablet makers to go for a slim-bezel design by sticking a camera in the screen itself.
I can’t imagine folks who care about gaming enough to want a 240 Hz display also want a permanent obstruction in the screen. But there’s no word on whether the camera cut-out is optional or mandatory.
There’s no word on if or when we’ll see tablets with the new display. But it seems like TCL figures there’s a market for gaming tablets or it wouldn’t have made the display.

SWITCHOFFSET
FunctionChanges the time zone offset of a date/time string without affecting the date and time parts. For instance, the string "2016-07-23 22:21:35.870 -04:00" can be converted to "2016-07-23 22:21:35.870 +05:30", using a new time zone offset of "+05:30". This function is intended for use when a date/time was wrongly imported with an incorrect time zone, and the user wishes to change the time zone offset without changing the date and time part of the string.
SWITCHOFFSET(date, time-zone)
Returns a date/time string containing the original date and time with the new time zone offset.
PRINT SWITCHOFFSET('2016-07-23 22:27:29.940 -06:00', '+04:00');
PRINT SWITCHOFFSET('2016-07-23 22:27:29.940 -06:00', -240);

System Architect Symbol details for "Percept"
Agent (Class)
- Child Diagrams:
-
Agent (
UML Class)
Description:
Role of a subject enabling it to act purposefully.
Comment:
CBS V2: - A role of a "Subject" which indicates that it has power to act
This is a role which may be played by a "Subject". Sometimes, an "Agent" may be created in order to
assemble a set of responsibilities and authorities prior to a specific "Subject" being identified
and allocated to it.
For purposes of creating an "Authorising Act", an "Agent" may actually be a group of individuals -
for example when joint responsibility is being taken for some decision, as in a clinical case
conference. In such a case the details of the group are taken care of by "Subject" and "Inter
Subject Relationship".
Examples of "Agent":
Dr Smithers within NHS XYZ Trust,
Ms J.Doe in the HXT Pathology laboratory.
A better understanding of the types of "Agent" can be gained from examination of its subtypes.
Concept (Class)

including:
The "Object" of interest to an "Agent" (CBS v2).
One or a collection of physical objects.
"Percept" which is a physical object and / or a collection of physical objects.
Persistent perceivable object.
Extension of one or more "Concepts" which is perceived or inferred to exist in the universe.

public final class TorchCallbacks
extends java.lang.Object
All available callbacks are in this class, from here you can subscribe, or un-subscribe from a callback.
To subscribe to a callback, you will need either an anonymous class, or a lambda. You will also have to store the callback in a variable, if you don't store it in a variable, you will be unable to remove the callback.
Lambda example:
ICharPressedCallback charPressedCallback;
charPressedCallback = (c) -> onCharPressed(c)
;
private void onCharPressed(char c)
{
Logger.log("Character " + c + " has been pressed");
}
Anonymous class example:
ICharPressedCallback charPressedCallback;
charPressedCallback = new ICharPressedCallback()
{
@Override
public void onCharPressed(char c)
{
Logger.log("Character " + c + " has been pressed");
}
};
Subscribing and un-subscribing:
TorchCallbacks.onCharPressed.addListener(charPressedCallback); TorchCallbacks.onCharPressed.removeListener(charPressedCallback);

Gulf Energy inks agreement to study building of 6,000 MW LNG power plant in Vietnam National
Prime Minister of the Socialist Republic of Vietnam Nguyen Xuan Phuc together with Vietnam’s Minister of Industry and Trade Tran Tuan Anh on Saturday (November 2) presided over the signing of a cooperation agreement for the development of an integrated LNG-power project in Vietnam’s Ninh Thuan province between Gulf Energy Development Public Co Ltd (Gulf) and Luu Xuan Vinh, president of Ninh Thuan Provincial People’s Committee.
The signing, held on the sidelines of the 35th Asean Summit and Related Summits at Impact Muang Thong Thani, was led on the Thai side by Gulf’s president Porntipa Chinvetkitvanit, former Supreme Court president Cheep Jullamon and former Minister of Energy Viset Choopiban.
The project aims to study the feasibility of building a liquid natural gas (LNG) power plant with the capacity of 6,000 megawatts and fully equipped with a LNG processing and distribution station to support economic and urban expansion in the Southeastern region of Vietnam.


This widget allows us to change the font size of a specified page element.
To use this widget, we need to use a couple of attributes. We can use the set method (i.e. grouping all of the widget components in a single div with the attribute data-ur-set) or the id method (i.e. giving each component of the widget a data-ur-id with an identical value, which doesn't require them to be grouped inside a single wrapper).

Ever wondered what your zodiac says about your profession?
You won't find a straight answer here!
This one isn't really a profession :) Think of it as to which zodiac sign you'd belong if you were born on a random day in a non-leap year (365 days).
Why not a straight line? Well, each sign isn't contained in the same amount of days in a year. So if we had an infinite amount of people we'd have the same distribution.
Among the people entites parsed from freebase on 2014 September 22. this is the distribution of zodiac signs:
There were in fact about 3.3M person entities, but not all had birth dates in a form that could be salvaged; missing day, or even month, in most cases no birth date at all.
I've also generated a simulated population of our planet. I've taken estimate of people from World Meters and rounded it to something sensible.
I intentionally didn't superimpose "Birhted" onto this chart, because the main line wouldn't be visible if I did.
This one is interesting and telling. It's, in my opinion, the reason for the subtitle.
If you have a little courage to draw a line through this dataset you will realize one thing: the more members you have in a group, there's less indication that one profession suits one sign better than the others.
If there was a dataset large enough to cover every employed person on the planet, one would realize that there is no visible or otherwise notable correlation between zodiac signs and chosen profession.


I don't really want him here but I can't get him off either. So I just decided
to make the best out of a bad situation and give him a nice place to live.
States
-
Happy
- Bill is happy.
- You can make Bill more happy by giving him some balloons
-
Thirsty
- Bill requires liquid
- Try giving Bill a drink to make him less thirsty
-
Hungry
- Bill is hungry
- Give Bill food to make him less hungry
-
Sad
- Bill is sad, this happens a lot :(
- But if you show Bill some balloons he won't be sad anymore
-
Tired
- Bill is tired
- Give Bill an energy drink to wake him up.
Behind the scenes
Behind the scenes Bill's state's are driven by Markov chains. Every second the Virtual
Pest calculates its next state. Each state has a set of probabilities associated with
changing to each other state (ex., if "hungry" there is a 20% chance Bill will be
"thirsty" next and 80% chance Bill will stay thirsty).
Each stimuli lessens the chance of a certain state occurring multiple times in a row. For
example the "Tired" state: Normally there is a 50% chance that Bill will remain tired in the
next state. By clicking the Energy Drink stimuli the chances of Bill being tired in the next
state is much less.

From the Mailing List:
I've mentioned this in the past and was wondering if anyone would be interested in changing the meeting dates. I'm personally interested because our meetings also occur on the same day as the Dirty Rectangles fellows which I've been wanting to go to for a while now.
We could perhaps move it from the 3rd Wednesday to the 3rd Tuesday of the month or would people prefer something else? These changes probably won't happen for another month or two.
Please join in the conversation on the mailing list.

NAME
elf - format of Executable and Linking Format (ELF) files
SYNOPSIS
#include <elf.h>
DESCRIPTION
The header file
<elf.h>
defines the format of ELF executable binary files.
Amongst these files are
normal executable files, relocatable object files, core files and shared
libraries.
An executable file using the ELF file format consists of an ELF header,
followed by a program header table or a section header table, or both.
The ELF header is always at offset zero of the file.
The program header
table and the section header table's offset in the file are defined in the
ELF header.
The two tables describe the rest of the particularities of
the file.
This header file describes the above mentioned headers as C structures
and also includes structures for dynamic sections, relocation sections and
symbol tables.
The following types are used for N-bit architectures (N=32,64,
ElfN
stands for
Elf32
or
Elf64,
uintN_t
stands for
uint32_t
or
uint64_t):
ElfN_Addr Unsigned program address, uintN_t
ElfN_Off Unsigned file offset, uintN_t
ElfN_Section Unsigned section index, uint16_t
ElfN_Versym Unsigned version symbol information, uint16_t
Elf_Byte unsigned char
ElfN_Half uint16_t
ElfN_Sword int32_t
ElfN_Word uint32_t
ElfN_Sxword int64_t
ElfN_Xword uint64_t
(Note: The *BSD terminology is a bit different.
There
Elf64_Half
is
twice as large as
Elf32_Half,
and
Elf64Quarter
is used for
uint16_t.
In order to avoid confusion these types are replaced by explicit ones
in the below.)
All data structures that the file format defines follow the
"natural"
size and alignment guidelines for the relevant class.
If necessary,
data structures contain explicit padding to ensure 4-byte alignment
for 4-byte objects, to force structure sizes to a multiple of 4, and so on.
The ELF header is described by the type
Elf32_Ehdr
or
Elf64_Ehdr:
#define EI_NIDENT 16
typedef struct {
unsigned char e_ident[EI_NIDENT];
uint16_t e_type;
uint16_t e_machine;
uint32_t e_version;
ElfN_Addr e_entry;
ElfN_Off e_phoff;
ElfN_Off e_shoff;
uint32_t e_flags;
uint16_t e_ehsize;
uint16_t e_phentsize;
uint16_t e_phnum;
uint16_t e_shentsize;
uint16_t e_shnum;
uint16_t e_shstrndx;
} ElfN_Ehdr;
The fields have the following meanings:
- e_ident
-
This array of bytes specifies to interpret the file,
independent of the processor or the file's remaining contents.
Within this array everything is named by macros, which start with
the prefix
EI_
and may contain values which start with the prefix
ELF.
The following macros are defined:
-
- EI_MAG0
-
The first byte of the magic number.
It must be filled with
ELFMAG0.
(0: 0x7f)
- EI_MAG1
-
The second byte of the magic number.
It must be filled with
ELFMAG1.
(1: 'E')
- EI_MAG2
-
The third byte of the magic number.
It must be filled with
ELFMAG2.
(2: 'L')
- EI_MAG3
-
The fourth byte of the magic number.
It must be filled with
ELFMAG3.
(3: 'F')
- EI_CLASS
-
The fifth byte identifies the architecture for this binary:
-
-
-
ELFCLASSNONE
This class is invalid.
- ELFCLASS32
-
This defines the 32-bit architecture.
It supports machines with files
and virtual address spaces up to 4 Gigabytes.
- ELFCLASS64
-
This defines the 64-bit architecture.
- EI_DATA
-
The sixth byte specifies the data encoding of the processor-specific
data in the file.
Currently these encodings are supported:
-
-
-
ELFDATANONE
Unknown data format.
- ELFDATA2LSB
-
Two's complement, little-endian.
- ELFDATA2MSB
-
Two's complement, big-endian.
-
-
EI_VERSION
The seventh byte is the version number of the ELF specification:
-
- EV_NONE
-
Invalid version.
- EV_CURRENT
-
Current version.
- EI_OSABI
-
The eighth byte identifies the operating system
and ABI to which the object is targeted.
Some fields in other ELF structures have flags
and values that have platform-specific meanings;
the interpretation of those fields is determined by the value of this byte.
For example:
-
-
-
ELFOSABI_NONE
Same as ELFOSABI_SYSV
- ELFOSABI_SYSV
-
UNIX System V ABI.
- ELFOSABI_HPUX
-
HP-UX ABI.
- ELFOSABI_NETBSD
-
NetBSD ABI.
- ELFOSABI_LINUX
-
Linux ABI.
- ELFOSABI_SOLARIS
-
Solaris ABI.
- ELFOSABI_IRIX
-
IRIX ABI.
- ELFOSABI_FREEBSD
-
FreeBSD ABI.
- ELFOSABI_TRU64
-
TRU64 UNIX ABI.
- ELFOSABI_ARM
-
ARM architecture ABI.
- ELFOSABI_STANDALONE
-
Stand-alone (embedded) ABI.
- EI_ABIVERSION
-
The ninth byte identifies the version of the ABI
to which the object is targeted.
This field is used to distinguish among incompatible versions of an ABI.
The interpretation of this version number
is dependent on the ABI identified by the
EI_OSABI
field.
Applications conforming to this specification use the value 0.
- EI_PAD
-
Start of padding.
These bytes are reserved and set to zero.
Programs
which read them should ignore them.
The value for
EI_PAD
will change in
the future if currently unused bytes are given meanings.
- EI_NIDENT
-
The size of the
e_ident
array.
- e_type
-
This member of the structure identifies the object file type:
-
-
-
ET_NONE
An unknown type.
- ET_REL
-
A relocatable file.
- ET_EXEC
-
An executable file.
- ET_DYN
-
A shared object.
- ET_CORE
-
A core file.
- e_machine
-
This member specifies the required architecture for an individual file.
For example:
-
-
-
EM_NONE
An unknown machine.

-
SPARC with enhanced instruction set.
- EM_PPC
-
PowerPC.
- EM_PPC64
-

- EM_S390
-
IBM S/390
- EM_ARM
-

- EM_IA_64
-
Intel Itanium
- EM_X86_64
-
AMD x86-64
- EM_VAX
-

- e_version
-
This member identifies the file version:
-
-
-
EV_NONE
Invalid version.
- EV_CURRENT
-
Current version.
- e_entry
-
This member gives the virtual address to which the system first transfers
control, thus starting the process.
If the file has no associated entry
point, this member holds zero.
- e_phoff
-
This member holds the program header table's file offset in bytes.
If
the file has no program header table, this member holds zero.
- e_shoff
-
This member holds the section header table's file offset in bytes.
If the
file has no section header table, this member holds zero.
- e_flags
-
This member holds processor-specific flags associated with the file.
Flag names take the form EF_`machine_flag'.
Currently no flags have been defined.
- e_ehsize
-
This member holds the ELF header's size in bytes.
- e_phentsize
-
This member holds the size in bytes of one entry in the file's program header
table; all entries are the same size.
- e_phnum
-
This member holds the number of entries in the program header
table.
Thus the product of
e_phentsize
and
e_phnum
gives the table's size
in bytes.
If a file has no program header,
e_phnum
holds the value zero.
-
If the number of entries in the program header table is larger than or equal to
PN_XNUM
(0xffff), this member holds
PN_XNUM
(0xffff) and the real number of entries in the program header table is held
in the
sh_info
member of the initial entry in section header table.
Otherwise, the
sh_info
member of the initial entry contains the value zero.
-
- PN_XNUM
-
This is defined as 0xffff, the largest number
e_phnum
can have, specifying where the actual number of program headers is assigned.
-
- e_shentsize
-
This member holds a sections header's size in bytes.
A section header is one
entry in the section header table; all entries are the same size.
- e_shnum
-
This member holds the number of entries in the section header table.
Thus
the product of
e_shentsize
and
e_shnum
gives the section header table's size in bytes.
If a file has no section
header table,
e_shnum
holds the value of zero.
-
If the number of entries in the section header table is larger than or equal to
SHN_LORESERVE
(0xff00),
e_shnum
holds the value zero and the real number of entries in the section header
table is held in the
sh_size
member of the initial entry in section header table.
Otherwise, the
sh_size
member of the initial entry in the section header table holds the value zero.
- e_shstrndx
-
This member holds the section header table index of the entry associated
with the section name string table.
If the file has no section name string
table, this member holds the value
SHN_UNDEF.
-
If the index of section name string table section is larger than or equal to
SHN_LORESERVE
(0xff00), this member holds
SHN_XINDEX
(0xffff) and the real index of the section name string table section
is held in the
sh_link
member of the initial entry in section header table.
Otherwise, the
sh_link
member of the initial entry in section header table contains the value zero.
-
- SHN_UNDEF
-
This value marks an undefined, missing, irrelevant, or otherwise meaningless
section reference.
For example, a symbol
"defined"
relative to section number
SHN_UNDEF
is an undefined symbol.
- SHN_LORESERVE
-
This value specifies the lower bound of the range of reserved indices.
- SHN_LOPROC
-
Values greater than or equal to
SHN_HIPROC
are reserved for processor-specific semantics.
- SHN_HIPROC
-
Values less than or equal to
SHN_LOPROC
are reserved for processor-specific semantics.
- SHN_ABS
-
This value specifies absolute values for the corresponding reference.
For
example, symbols defined relative to section number
SHN_ABS
have absolute values and are not affected by relocation.
- SHN_COMMON
-
Symbols defined relative to this section are common symbols, such as Fortran
COMMON or unallocated C external variables.
- SHN_HIRESERVE
-
This value specifies the upper bound of the range of reserved
indices between
SHN_LORESERVE
and
SHN_HIRESERVE,
inclusive; the values do
not reference the section header table.
That is, the section header table
does
not
contain entries for the reserved indices.
An executable or shared object file's program header table is an array of
structures, each describing a segment or other information the system needs
to prepare the program for execution.
An object file
segment
contains one or more
sections.
Program headers are meaningful only for executable and shared object files.
A file specifies its own program header size with the ELF header's
e_phentsize
and
e_phnum
members.
The ELF program header is described by the type
Elf32_Phdr
or
Elf64_Phdr
depending on the architecture:
typedef struct {
uint32_t p_type;
Elf32_Off p_offset;
Elf32_Addr p_vaddr;
Elf32_Addr p_paddr;
uint32_t p_filesz;
uint32_t p_memsz;
uint32_t p_flags;
uint32_t p_align;
} Elf32_Phdr;
typedef struct {
uint32_t p_type;
uint32_t p_flags;
Elf64_Off p_offset;
Elf64_Addr p_vaddr;
Elf64_Addr p_paddr;
uint64_t p_filesz;
uint64_t p_memsz;
uint64_t p_align;
} Elf64_Phdr;
The main difference between the 32-bit and the 64-bit program header lies
in the location of the
p_flags
member in the total struct.
- p_type
-
This member of the Phdr struct tells what kind of segment this array
element describes or how to interpret the array element's information.
-
- PT_NULL
-
The array element is unused and the other members' values are undefined.
This lets the program header have ignored entries.
- PT_LOAD
-
The array element specifies a loadable segment, described by
p_filesz
and
p_memsz.
The bytes from the file are mapped to the beginning of the memory
segment.
If the segment's memory size
p_memsz
is larger than the file size
p_filesz,
the
"extra"
bytes are defined to hold the value 0 and to follow the segment's
initialized area.
The file size may not be larger than the memory size.
Loadable segment entries in the program header table appear in ascending
order, sorted on the
p_vaddr
member.
- PT_DYNAMIC
-
The array element specifies dynamic linking information.
- PT_INTERP
-
The array element specifies the location and size of a null-terminated
pathname to invoke as an interpreter.
This segment type is meaningful
only for executable files (though it may occur for shared objects).
However it may not occur more than once in a file.
If it is present, it must precede any loadable segment entry.
- PT_NOTE
-
The array element specifies the location and size for auxiliary information.
- PT_SHLIB
-
This segment type is reserved but has unspecified semantics.
Programs that
contain an array element of this type do not conform to the ABI.
- PT_PHDR
-
The array element, if present, specifies the location and size of the program
header table itself, both in the file and in the memory image of the program.
This segment type may not occur more than once in a file.
Moreover, it may
occur only if the program header table is part of the memory image of the
program.
If it is present, it must precede any loadable segment entry.
- PT_LOPROC
-
Values greater than or equal to
PT_HIPROC
are reserved for processor-specific semantics.
- PT_HIPROC
-
Values less than or equal to
PT_LOPROC
are reserved for processor-specific semantics.
- PT_GNU_STACK
-
GNU extension which is used by the Linux kernel to control the state of the
stack via the flags set in the
p_flags
member.
- p_offset
-
This member holds the offset from the beginning of the file at which
the first byte of the segment resides.
- p_vaddr
-
This member holds the virtual address at which the first byte of the
segment resides in memory.
- p_paddr
-
On systems for which physical addressing is relevant, this member is
reserved for the segment's physical address.
Under
BSD
this member is
not used and must be zero.
- p_filesz
-
This member holds the number of bytes in the file image of the segment.
It may be zero.
- p_memsz
-
This member holds the number of bytes in the memory image of the segment.
It may be zero.
- p_flags
-
This member holds a bit mask of flags relevant to the segment:
-
-
-
PF_X
An executable segment.
- PF_W
-
A writable segment.
- PF_R
-
A readable segment.
-
A text segment commonly has the flags
PF_X
and
PF_R.
A data segment commonly has
PF_X,
PF_W
and
PF_R.
- p_align
-
This member holds the value to which the segments are aligned in memory
and in the file.
Loadable process segments must have congruent values for
p_vaddr
and
p_offset,
modulo the page size.
Values of zero and one mean no alignment is required.
Otherwise,
p_align
should be a positive, integral power of two, and
p_vaddr
should equal
p_offset,
modulo
p_align.
A file's section header table lets one locate all the file's sections.
The
section header table is an array of
Elf32_Shdr
or
Elf64_Shdr
structures.
The
ELF header's
e_shoff
member gives the byte offset from the beginning of the file to the section
header table.
e_shnum
holds the number of entries the section header table contains.
e_shentsize
holds the size in bytes of each entry.
A section header table index is a subscript into this array.
Some section
header table indices are reserved:
the initial entry and the indices between
SHN_LORESERVE
and
SHN_HIRESERVE.
The initial entry is used in ELF extensions for
e_phnum,
e_shnum
and
e_strndx;
in other cases, each field in the initial entry is set to zero.
An object file does not have sections for
these special indices:
-
- SHN_UNDEF
-
This value marks an undefined, missing, irrelevant, or otherwise meaningless
section reference.
- SHN_LORESERVE
-
This value specifies the lower bound of the range of reserved indices.
- SHN_LOPROC
-
Values greater than or equal to
SHN_HIPROC
are reserved for processor-specific semantics.
- SHN_HIPROC
-
Values less than or equal to
SHN_LOPROC
are reserved for processor-specific semantics.
- SHN_ABS
-
This value specifies the absolute value for the corresponding reference.
For
example, a symbol defined relative to section number
SHN_ABS
has an absolute value and is not affected by relocation.
- SHN_COMMON
-
Symbols defined relative to this section are common symbols, such as FORTRAN
COMMON or unallocated C external variables.
- SHN_HIRESERVE
-
This value specifies the upper bound of the range of reserved indices.
The
system reserves indices between
SHN_LORESERVE
and
SHN_HIRESERVE,
inclusive.
The section header table does not contain entries for the
reserved indices.
The section header has the following structure:
typedef struct {
uint32_t sh_name;
uint32_t sh_type;
uint32_t sh_flags;
Elf32_Addr sh_addr;
Elf32_Off sh_offset;
uint32_t sh_size;
uint32_t sh_link;
uint32_t sh_info;
uint32_t sh_addralign;
uint32_t sh_entsize;
} Elf32_Shdr;
typedef struct {
uint32_t sh_name;
uint32_t sh_type;
uint64_t sh_flags;
Elf64_Addr sh_addr;
Elf64_Off sh_offset;
uint64_t sh_size;
uint32_t sh_link;
uint32_t sh_info;
uint64_t sh_addralign;
uint64_t sh_entsize;
} Elf64_Shdr;
No real differences exist between the 32-bit and 64-bit section headers.
- sh_name
-
This member specifies the name of the section.
Its value is an index
into the section header string table section, giving the location of
a null-terminated string.
- sh_type
-
This member categorizes the section's contents and semantics.
-
- SHT_NULL
-
This value marks the section header as inactive.
It does not
have an associated section.
Other members of the section header
have undefined values.
- SHT_PROGBITS
-
This section holds information defined by the program, whose
format and meaning are determined solely by the program.
- SHT_SYMTAB
-
This section holds a symbol table.
Typically,
SHT_SYMTAB
provides symbols for link editing, though it may also be used
for dynamic linking.
As a complete symbol table, it may contain
many symbols unnecessary for dynamic linking.
An object file can
also contain a
SHT_DYNSYM
section.
- SHT_STRTAB
-
This section holds a string table.
An object file may have multiple
string table sections.
- SHT_RELA
-
This section holds relocation entries with explicit addends, such
as type
Elf32_Rela
for the 32-bit class of object files.
An object may have multiple
relocation sections.
- SHT_HASH
-
This section holds a symbol hash table.
An object participating in
dynamic linking must contain a symbol hash table.
An object file may
have only one hash table.
- SHT_DYNAMIC
-
This section holds information for dynamic linking.
An object file may
have only one dynamic section.
- SHT_NOTE
-
This section holds information that marks the file in some way.
- SHT_NOBITS
-
A section of this type occupies no space in the file but otherwise
resembles
SHT_PROGBITS.
Although this section contains no bytes, the
sh_offset
member contains the conceptual file offset.
- SHT_REL
-
This section holds relocation offsets without explicit addends, such
as type
Elf32_Rel
for the 32-bit class of object files.
An object file may have multiple
relocation sections.
- SHT_SHLIB
-
This section is reserved but has unspecified semantics.
- SHT_DYNSYM
-
This section holds a minimal set of dynamic linking symbols.
An
object file can also contain a
SHT_SYMTAB
section.
- SHT_LOPROC
-
This value up to and including
SHT_HIPROC
is reserved for processor-specific semantics.
- SHT_HIPROC
-
This value down to and including
SHT_LOPROC
is reserved for processor-specific semantics.
- SHT_LOUSER
-
This value specifies the lower bound of the range of indices reserved for
application programs.
- SHT_HIUSER
-
This value specifies the upper bound of the range of indices reserved for
application programs.
Section types between
SHT_LOUSER
and
SHT_HIUSER
may be used by the application, without conflicting with current or future
system-defined section types.
- sh_flags
-
Sections support one-bit flags that describe miscellaneous attributes.
If a flag bit is set in
sh_flags,
the attribute is
"on"
for the section.
Otherwise, the attribute is
"off"
or does not apply.
Undefined attributes are set to zero.
-
- SHF_WRITE
-
This section contains data that should be writable during process
execution.
- SHF_ALLOC
-
This section occupies memory during process execution.
Some control
sections do not reside in the memory image of an object file.
This
attribute is off for those sections.
- SHF_EXECINSTR
-
This section contains executable machine instructions.
- SHF_MASKPROC
-
All bits included in this mask are reserved for processor-specific
semantics.
- sh_addr
-
If this section appears in the memory image of a process, this member
holds the address at which the section's first byte should reside.
Otherwise, the member contains zero.
- sh_offset
-
This member's value holds the byte offset from the beginning of the file
to the first byte in the section.
One section type,
SHT_NOBITS,
occupies no space in the file, and its
sh_offset
member locates the conceptual placement in the file.
- sh_size
-
This member holds the section's size in bytes.
Unless the section type
is
SHT_NOBITS,
the section occupies
sh_size
bytes in the file.
A section of type
SHT_NOBITS
may have a nonzero size, but it occupies no space in the file.
- sh_link
-
This member holds a section header table index link, whose interpretation
depends on the section type.
- sh_info
-
This member holds extra information, whose interpretation depends on the
section type.
- sh_addralign
-
Some sections have address alignment constraints.
If a section holds a
doubleword, the system must ensure doubleword alignment for the entire
section.
That is, the value of
sh_addr
must be congruent to zero, modulo the value of
sh_addralign.
Only zero and positive integral powers of two are allowed.
Values of zero
or one mean the section has no alignment constraints.
- sh_entsize
-
Some sections hold a table of fixed-sized entries, such as a symbol table.
For such a section, this member gives the size in bytes for each entry.
This member contains zero if the section does not hold a table of
fixed-size entries.
Various sections hold program and control information:
- .bss
-
This section holds uninitialized data that contributes to the program's
memory image.
By definition, the system initializes the data with zeros
when the program begins to run.
This section is of type
SHT_NOBITS.

SHF_ALLOC
bit.
Whether the
SHF_WRITE
bit is set is processor-specific.

SHT_DYNAMIC.
See the attributes above.
- .dynstr
-
This section holds strings needed for dynamic linking, most commonly
the strings that represent the names associated with symbol table entries.
This section is of type
SHT_STRTAB.
The attribute type used is
SHF_ALLOC.

String table sections hold null-terminated character sequences, commonly
called strings.
The object file uses these strings to represent symbol
and section names.
One references a string as an index into the string
table section.
The first byte, which is index zero, is defined to hold
a null byte ('\0').
Similarly, a string table's last byte is defined to
hold a null byte, ensuring null termination for all strings.
An object file's symbol table holds information needed to locate and
relocate a program's symbolic definitions and references.
A symbol table
index is a subscript into this array.
typedef struct {
uint32_t st_name;
Elf32_Addr st_value;
uint32_t st_size;
unsigned char st_info;
unsigned char st_other;
uint16_t st_shndx;
} Elf32_Sym;
typedef struct {
uint32_t st_name;
unsigned char st_info;
unsigned char st_other;
uint16_t st_shndx;
Elf64_Addr st_value;
uint64_t st_size;
} Elf64_Sym;
The 32-bit and 64-bit versions have the same members, just in a different
order.
- st_name
-
This member holds an index into the object file's symbol string table,
which holds character representations of the symbol names.
If the value
is nonzero, it represents a string table index that gives the symbol
name.
Otherwise, the symbol table has no name.
- st_value
-
This member gives the value of the associated symbol.
- st_size
-
Many symbols have associated sizes.
This member holds zero if the symbol
has no size or an unknown size.
- st_info
-
This member specifies the symbol's type and binding attributes:
-
- STT_NOTYPE
-
The symbol's type is not defined.
- STT_OBJECT
-
The symbol is associated with a data object.
- STT_FUNC
-
The symbol is associated with a function or other executable code.
- STT_SECTION
-
The symbol is associated with a section.
Symbol table entries of
this type exist primarily for relocation and normally have
STB_LOCAL
bindings.
- STT_FILE
-
By convention, the symbol's name gives the name of the source file
associated with the object file.
A file symbol has
STB_LOCAL
bindings, its section index is
SHN_ABS,
and it precedes the other
STB_LOCAL
symbols of the file, if it is present.
- STT_LOPROC
-
This value up to and including
STT_HIPROC
is reserved for processor-specific semantics.
- STT_HIPROC
-
This value down to and including
STT_LOPROC
is reserved for processor-specific semantics.
- STB_LOCAL
-
Local symbols are not visible outside the object file containing their
definition.
Local symbols of the same name may exist in multiple files
without interfering with each other.
- STB_GLOBAL
-
Global symbols are visible to all object files being combined.
One file's
definition of a global symbol will satisfy another file's undefined
reference to the same symbol.
- STB_WEAK
-
Weak symbols resemble global symbols, but their definitions have lower
precedence.
- STB_LOPROC
-
This value up to and including
STB_HIPROC
is reserved for processor-specific semantics.
- STB_HIPROC
-
This value down to and including
STB_LOPROC
is reserved for processor-specific semantics.
-
There are macros for packing and unpacking the binding and type fields:
-
ELF32_ST_BIND(info)
or
ELF64_ST_BIND(info)
extract a binding from an
st_info
value.
-
ELF32_ST_TYPE(info)
or
ELF64_ST_TYPE(info)
extract a type from an
st_info
value.
-
ELF32_ST_INFO(bind, type)
or
ELF64_ST_INFO(bind, type)
convert a binding and a type into an
st_info
value.
- st_other
-
This member defines the symbol visibility.
-
-
-
STV_DEFAULT
Default symbol visibility rules.
- STV_INTERNAL
-
Processor-specific hidden class.
- STV_HIDDEN
-
Symbol is unavailable in other modules.
- STV_PROTECTED
-
Not preemptible, not exported.
There are macros for extracting the visibility type:
ELF32_ST_VISIBILITY(other)
or
ELF64_ST_VISIBILITY(other)
- st_shndx
-
Every symbol table entry is
"defined"
in relation to some section.
This member holds the relevant section
header table index.
Relocation is the process of connecting symbolic references with
symbolic definitions.
Relocatable files must have information that
describes how to modify their section contents, thus allowing executable
and shared object files to hold the right information for a process's
program image.
Relocation entries are these data.
Relocation structures that do not need an addend:
typedef struct {
Elf32_Addr r_offset;
uint32_t r_info;
} Elf32_Rel;
typedef struct {
Elf64_Addr r_offset;
uint64_t r_info;
} Elf64_Rel;
Relocation structures that need an addend:
typedef struct {
Elf32_Addr r_offset;
uint32_t r_info;
int32_t r_addend;
} Elf32_Rela;
typedef struct {
Elf64_Addr r_offset;
uint64_t r_info;
int64_t r_addend;
} Elf64_Rela;
- r_offset
-
This member gives the location at which to apply the relocation action.
For a relocatable file, the value is the byte offset from the beginning
of the section to the storage unit affected by the relocation.
For an
executable file or shared object, the value is the virtual address of
the storage unit affected by the relocation.
- r_info
-
This member gives both the symbol table index with respect to which the
relocation must be made and the type of relocation to apply.
Relocation
types are processor-specific.
When the text refers to a relocation
entry's relocation type or symbol table index, it means the result of
applying
ELF[32|64]_R_TYPE
or
ELF[32|64]_R_SYM,
respectively, to the entry's
r_info
member.
- r_addend
-
This member specifies a constant addend used to compute the value to be
stored into the relocatable field.
The .dynamic section contains a series of structures that hold relevant
dynamic linking information.
The d_tag member controls the interpretation
of d_un.
typedef struct {
Elf32_Sword d_tag;
union {
Elf32_Word d_val;
Elf32_Addr d_ptr;
} d_un;
} Elf32_Dyn;
extern Elf32_Dyn _DYNAMIC[];
typedef struct {
Elf64_Sxword d_tag;
union {
Elf64_Xword d_val;
Elf64_Addr d_ptr;
} d_un;
} Elf64_Dyn;
extern Elf64_Dyn _DYNAMIC[];

these addresses, the actual address should be computed based on the
original file value and memory base address.
Files do not contain
relocation entries to fixup these addresses.
