| H A D | pipe.h | diff 13907 Sun Feb 04 17:56:35 MST 1996 dyson Improve the performance for pipe(2) again. Also include some fixes for previous version of new pipes from Bruce Evans. This new version: Supports more properly the semantics of select (BDE). Supports "OLD_PIPE" correctly (kern_descrip.c, BDE). Eliminates incorrect EPIPE returns (bash 'pipe broken' messages.) Much faster yet, currently tuned relatively conservatively -- but now gives approx 50% more perf than the new pipes code did originally. (That was about 50% more perf than the original BSD pipe code.) Known bugs outstanding: No support for async io (SIGIO). Will be included soon. Next to do: Merge support for FIFOs.
