NAME
       SDL_SemPost - Unlock a semaphore.

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

       int SDL_SemPost(SDL_sem *sem);

DESCRIPTION
       SDL_SemPost  unlocks  the  semaphore pointed to by sem and atomically increments the sema-
       phores value. Threads that were blocking on the semaphore may be scheduled after this call
       succeeds.

       SDL_SemPost  should  be	called	after  a  semaphore  is  locked  by  a successful call to
       SDL_SemWait, SDL_SemTryWait or SDL_SemWaitTimeout.

RETURN VALUE
       Returns 0 if successful or -1 if there was an error (leaving the semaphore unchanged).

EXAMPLES
       SDL_SemPost(my_sem);

SEE ALSO
       SDL_CreateSemaphore, SDL_DestroySemaphore, SDL_SemWait,	SDL_SemTryWait,  SDL_SemWaitTime-
       out, SDL_SemValue
