NAME
       SDL_DestroySemaphore  -  Destroys  a  semaphore  that  was  created  by
       SDL_CreateSemaphore.

SYNOPSIS
       #include "SDL.h" #include "SDL_thread.h"

       void SDL_DestroySemaphore(SDL_sem *sem);

DESCRIPTION
       SDL_DestroySemaphore destroys the semaphore pointed to by sem that  was
       created  by  SDL_CreateSemaphore. It is not safe to destroy a semaphore
       if there are threads currently blocked waiting on it.

EXAMPLES
       if (my_sem != NULL) {
               SDL_DestroySemaphore(my_sem);
               my_sem = NULL;
       }
