SDL_mutexP - Lock a mutex

       Locks  the  mutex, which was previously created with SDL_CreateMutex. If the mutex is already locked then
       SDL_mutexP will not return until it is unlocked. Returns 0 on success, or -1 on an error.

       SDL also defines a macro #defineSDL_LockMutex(m)SDL_mutexP(m).
