- * Function:  sem_getvalue
- *
- * Description:
- *   This function updates the location referenced by 'sval' argument to
- *   have the value of the semaphore referenced by 'sem' without effecting
- *   the state of the semaphore.  The updated value represents the actual
- *   semaphore value that occurred at some unspecified time during the call,
- *   but may not reflect the actual value of the semaphore when it is
- *   returned to the calling task.
- *
- *   If 'sem' is locked, the value return by sem_getvalue() will either be
- *   zero or a negative number whose absolute value represents the number
- *   of tasks waiting for the semaphore.
- *
- * Parameters:
- *   sem - Semaphore descriptor
- *   sval - Buffer by which the value is returned
- *
- * Return Value:
- *   0 (OK), or -1 (ERROR) if unsuccessful
- *
- * Assumptions:

- * Function: sem_init
- *
- * Description:
- *   This function initializes the UNAMED semaphore sem. Following a
- *   successful call to sem_init(), the semaophore may be used in subsequent
- *   calls to sem_wait(), sem_post(), and sem_trywait().  The semaphore
- *   remains usable until it is destroyed.
- *
- *   Only sem itself may be used for performing synchronization. The result
- *   of referring to copies of sem in calls to sem_wait(), sem_trywait(),
- *   sem_post(), and sem_destroy() is undefined.
- *
- * Parameters:
- *   sem - Semaphore to be initialized
- *   pshared - Process sharing (not used)
- *   value - Semaphore initialization value
- *
- * Return Value:
- *   0 (OK), or -1 (ERROR) if unsuccessful.
