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 sem‐
       aphore may be scheduled after this call succeeds.

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

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

EXAMPLES
       SDL_SemPost(my_sem);

SEE ALSO
       SDL_CreateSemaphore, SDL_DestroySemaphore, SDL_SemWait, SDL_SemTryWait,
       SDL_SemWaitTimeout, SDL_SemValue
