"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);
"SEE ALSO"
SDL_CreateSemaphore, SDL_DestroySemaphore, SDL_SemWait, SDL_SemTryWait, SDL_SemWaitTimeout, SDL_SemValue
