Typedef Documentation

typedef RTI_UINT32 OSAPI_ThreadOptions

Thread options

typedef RTI_BOOL(* OSAPI_ThreadRoutine)(struct OSAPI_ThreadInfo *thread_info)

Function Documentation

RTI_BOOL OSAPI_Thread_wakeup

(

struct OSAPI_Thread *

self

)

Wakeup user-thread.

If a user-defined thread function is blocking, e.g. waiting for data, and the user wants to delete the thread, it is necessary to unblock the user-thread. The user must provide a function which can unblock a thread. This function calls the wake up function to wake up a blocked user thread.

Parameters:

[in]

self

OSAPI_Thread to wakeup

Returns:

RTI_TRUE on success, RTI_FALSE on failure.

See also:

OSAPI_Thread_start

RTI_BOOL OSAPI_Thread_start

(

struct OSAPI_Thread *

me

)

Start a specific thread.

Parameters:

[in]

me

Thread to wake up

Returns:

RTI_TRUE on success, RTI_FALSE on failure.

See also:

OSAPI_Thread_create

RTI_BOOL OSAPI_Thread_destroy

(

struct OSAPI_Thread *

self

)

Destroy a specific thread.

Parameters:

[in]

self

Thread.

Returns:

RTI_TRUE on success, RTI_FALSE on failure.

See also:

OSAPI_Thread_create

void OSAPI_Thread_sleep

(

RTI_UINT32

ms

)

Suspend a thread for a specified amount of time.

Parameters:

[in]

ms

Sleep time.

void OSAPI_Thread_nanosleep

(

RTI_UINT32

ns

)

Suspend a thread for a specified amount of time in nanosec.

Parameters:

[in]

ns

Sleep time.

struct OSAPI_Thread* OSAPI_Thread_create ( const char *  name, const struct OSAPI_ThreadProperty *  properties, OSAPI_ThreadRoutine  user_routine, void *  user_data, OSAPI_ThreadRoutine  wakeup_routine  )

read

Create a thread.

Parameters:

[in]	name	The name of the thread.
[in]	properties	Thread properties. These properties are hints.
[in]	user_routine	Thread task. The thread task cannot assume that it can block; thus it must be written such that it can be called repeatedly.
[in]	user_data	Parameters passed to the thread task.
[in]	wakeup_routine	Routine to wake up a thread, called to delete a thread.

Returns:

Handle to stopped thread on success, NULL on failure.

See also:

OSAPI_Thread_destroy

OSAPI_ThreadId OSAPI_Thread_self

(

void

)

Return thread ID.

Returns:

thread ID of the calling thread.
