Date: Sat, 17 Sep 2005 13:38:49 +0200 From: Jon Daniel <forcemaster@gmx.net> To: sdl@libsdl.org Subject: [SDL] SDL_SemWaitTimeout patch for BeOS The current SDL-1.2.9/src/thread/beos/SDL_syssem.c returns -1 if the acquire_sem timeouts which according to the DocWiki is not correct. I've added support for the B_TIMED_OUT and B_WOULD_BLOCK in the switch. Jon Daniel
