- * Name:  sem_close
- *
- * Description:
- *   This function is called to indicate that the calling task is finished
- *   with the specified named semaphore, 'sem'.  The sem_close() deallocates
- *   any system resources allocated by the system for this named semaphore.
- *
- *   If the semaphore has not been removed with a call to sem_unlink(), then
- *   sem_close() has no effect on the named semaphore.  However, when the
- *   named semaphore has been fully unlinked, the semaphore will vanish when
- *   the last task closes it.
- *
- * Parameters:
- *  sem - semaphore descriptor
- *
- * Return Value:
- *  0 (OK), or -1 (ERROR) if unsuccessful.
- *
- * Assumptions:
- *   - Care must be taken to avoid risking the deletion of a semaphore that
- *     another calling task has already locked.
- *   - sem_close must not be called for an un-named semaphore
- *
