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);
