sem_destroy(3c)

sem_destroy(3C)          Standard C Library Functions          sem_destroy(3C)

NAME
       sem_destroy - destroy an unnamed semaphore

SYNOPSIS
       #include <semaphore.h>

       int sem_destroy(sem_t *sem);

DESCRIPTION
       The sem_destroy() function is used to destroy the unnamed semaphore in‐
       dicated  by  sem.  Only a semaphore that was created using sem_init(3C)
       may be destroyed using sem_destroy(); the  effect  of  calling  sem_de‐
       stroy()  with  a named semaphore is undefined. The effect of subsequent
       use of the semaphore sem is undefined until sem  is  re-initialized  by
       another call to sem_init(3C).


       It  is  safe  to destroy an initialised semaphore upon which no threads
       are currently blocked. The effect of destroying a semaphore upon  which
       other threads are currently blocked is undefined.

RETURN VALUES
       If  successful,  sem_destroy()  returns  0, otherwise it returns −1 and
       sets errno to indicate the error.

ERRORS
       The sem_destroy() function will fail if:

       EINVAL    The sem argument is not a valid semaphore.



       The sem_destroy() function may fail if:

       EBUSY    There are currently processes (or LWPs or threads) blocked  on
                the semaphore.
