Typedef Documentation

typedef struct OSAPI_Semaphore OSAPI_Semaphore_T

Abstract semaphore object.

OSAPI_Semaphore_T* OSAPI_Semaphore_new ( void )

Create a semaphore.

Returns:: Pointer to a semaphore with a value of 1 on success, NULL on failure.

RTI_BOOL OSAPI_Semaphore_delete ( OSAPI_Semaphore_T * self )

Delete a semaphore.

Parameters:

[in] self Semaphore created with OSAPI_Semaphore_new.

RTI_BOOL OSAPI_Semaphore_take	(	OSAPI_Semaphore_T *	self,
		RTI_INT32	timeout,
		RTI_INT32 *	fail_reason
	)

Take a semaphore.

Parameters:

[in]	self	Semaphore previously created with OSAPI_Semaphore_new.
[in]	timeout	Timeout in ms. The `take` call will wait at most `timeout` ms before returning. If OSAPI_SEMAPHORE_TIMEOUT_INFINITE is specified, the call will not return until the semaphore has a value of 1 or higher.
[out]	fail_reason	This parameter is not used, but present for compatibility reasons.

RTI_BOOL OSAPI_Semaphore_give ( OSAPI_Semaphore_T * self )

Give a semaphore.

Parameters:

[in] self Semaphore previously created with OSAPI_Semaphore_new.
