SDL_SemPost(3)							 SDL API Reference						    SDL_SemPost(3)

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 semaphores value. Threads that were blocking on the sema-
       phore 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);
