NAME
       sem_destroy - Destroys an unnamed semaphore (P1003.1b)

LIBRARY
       Realtime Library (librt.so, librt.a)

SYNOPSIS
       #include <semaphore.h>

       int sem_destroy (
       sem_t *sem);

PARAMETERS
       sem     References  the	unnamed semaphore to be destroyed.  Use the sem argument that was supplied to, and filled in by, the previous call
	       to sem_init.

DESCRIPTION
       The sem_destroy function destroys an unnamed semaphore indicated by sem.  Only a semaphore created using sem_init may  be  destroyed  using
       sem_destroy.

       The  potential  for deadlock exists if a process calls sem_destroy for a semaphore while there is a pending sem_wait, because a process may
       be waiting for a poster that has not yet opened the semaphore.

RETURN VALUES
       On successful completion, the function returns the value 0 (zero); otherwise, the function returns the value -1 and sets errno to  indicate
       the error, without destroying the semaphore indicated by the sem argument.

ERRORS
       The sem_destroy function fails under the following condition:

       [EINVAL]       The sem argument is not a valid semaphore.
