    Command:

    sem_destroy

    
    
    

    SYNOPSIS

           #include <semaphore.h>
    
           int sem_destroy(sem_t *sem);
    
           Link with -pthread.
    
    
    

    DESCRIPTION

           sem_destroy()  destroys the unnamed semaphore at the address pointed to
           by sem.
    
           Only a semaphore that has been initialized  by  sem_init(3)  should  be
           destroyed using sem_destroy().
    
           Destroying  a  semaphore  that other processes or threads are currently
           blocked on (in sem_wait(3)) produces undefined behavior.
    
           Using a semaphore that has been destroyed produces  undefined  results,
           until the semaphore has been reinitialized using sem_init(3).
    
    
    

    RETURN VALUE

           sem_destroy() returns 0 on success; on error, -1 is returned, and errno
           is set to indicate the error.
    
    
    

    ERRORS

           EINVAL sem is not a valid semaphore.
    
    
    

    ATTRIBUTES

       Multithreading (see pthreads(7))
           The sem_destroy() function is thread-safe.
    
    
    

    CONFORMING TO

           POSIX.1-2001.
    
    
    

    NOTES

           An unnamed semaphore should be destroyed with sem_destroy() before  the
           memory  in  which it is located is deallocated.  Failure to do this can
           result in resource leaks on some implementations.
