Macros
#define	OSAPI_SEMAPHORE_TIMEOUT_INFINITE -1
	If OSAPI_Semaphore_take is called with OSAPI_SEMAPHORE_TIMEOUT_INFINITE as timeout, OSAPI_Semaphore_take will not return until the semaphore is signaled.
#define	OSAPI_SEMAPHORE_RESULT_OK 0
	If OSAPI_Semaphore_take succeeds and the semaphore is signaled within the timeout period, OSAPI_Semaphore_take returns TRUE and sets the failure reason to OSAPI_SEMAPHORE_RESULT_OK.
#define	OSAPI_SEMAPHORE_RESULT_TIMEOUT 1
	If OSAPI_Semaphore_take was called with a timeout value different from OSAPI_SEMAPHORE_TIMEOUT_INFINITE, and the sempahore was not signaled before the timeout expired, waiting for the semaphore to unblock timed out, OSAPI_Semaphore_take TRUE and sets the failure reason to OSAPI_SEMAPHORE_RESULT_TIMEOUT.
#define	OSAPI_SEMAPHORE_RESULT_ERROR 2
	If OSAPI_Semaphore_take fails for an unknown reason, OSAPI_Semaphore_take returns FALSE and sets the failure reason to OSAPI_SEMAPHORE_RESULT_ERROR.

Typedefs
typedef struct OSAPI_Semaphore	OSAPI_Semaphore_T
	Abstract Semaphore type.
