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 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
