SDL_SemPost

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 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);
