Detailed Description

Common thread functions.

A thread is the smallest unit of execution within a process. Threads are parallel execution paths that can run independently but share the same resources, such as memory space, file descriptors, and other process-specific information. Threads enable concurrent execution and can be used to perform multiple tasks simultaneously within a single process.

Function Documentation

createThread()

Thread createThread	(	void(*)(void *)	function,
		void *	argument )

Creates a new thread executing the specified function.

Threads begin execution immediately upon construction of the associated thread object (pending any OS scheduling delays), starting at the top-level function provided as a constructor argument.

Parameters

[in]	function	pointer to the function that should be invoked
[in]	argument	argument that will be passed to the function or NULL

Returns

Thread instance on success, otherwise NULL.

destroyThread()

void destroyThread

(

Thread

thread

)

Destroys thread instance.

Parameters

thread

thread instance or NULL

joinThread()

void joinThread

(

Thread

thread

)

Blocks the current thread until the function execution end.

Parameters

thread

thread instance

sleepThread()

void sleepThread

(

double

delay

)

Blocks the execution of the current thread for a specified time.

Parameters

delay

thread sleep delay time (in seconds)

yieldThread()

bool yieldThread

(

)

Causes the current thread to yield execution to another thread.

Returns

True on success, otherwise false.

isThreadJoined()

bool isThreadJoined

(

Thread

thread

)

Returns thread current join status.

Parameters

thread

thread instance

isThreadCurrent()

bool isThreadCurrent

(

Thread

thread

)

Returns true if thread is currently running one.

Parameters

thread

thread instance

getThreadNative()

const void * getThreadNative

(

Thread

thread

)

Returns pointer to the native thread handle.

Warning

You should not free returned pointer or use it after thread destruction.

Parameters

thread

thread instance

isThreadMain()

bool isThreadMain

(

Thread

thread

)

Returns true if thread is main.

Parameters

thread

target thread instance

getThreadName()

void getThreadName	(	char *	name,
		size_t	size )

Returns current thread name.

Parameters

[out]	name	pointer to the thread name string
	size	maximal name string capacity (including '\0')

setThreadName()

void setThreadName

(

const char *

name

)

Sets current thread name.

Parameters

[in]

name

thread name string
