SDL_!SemPost- Unlock a semaphore.
!!SYNOPSIS


__#include
__


__int SDL_!SemPost__(__SDL_sem *sem__);
!!DESCRIPTION

after this call succeeds.

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__,
