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
       indicated by sem. Only a semaphore that was created using  sem_init(3C)
       may   be   destroyed   using   sem_destroy();  the  effect  of  calling
       sem_destroy() with a named semaphore is undefined. The effect of subse‐
       quent 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.
