- * _CORE_semaphore_Seize
- *
- * This routine attempts to allocate a core semaphore to the calling thread.
- *
- * Input parameters:
- * the_semaphore - pointer to semaphore control block
- * id - id of object to wait on
- * wait - TRUE if wait is allowed, FALSE otherwise
- * timeout - number of ticks to wait (0 means forever)
- *
- * Output parameters: NONE
- *
- * INTERRUPT LATENCY:
- * available
- * wait
