BJ> Looks like the BBS is using about half the cpu time BJ> on this system when max is running in console mode. You're right that this has to do with the way the keyboard is being polled: scott does this *often*; I don't know why he didn't hook a keyboard interrupt vector (or, if he did, how missed that usage. ;) It's not that expensive under my system, but this may have to do with how your version of curses implements non-blocking reads. One way to reduce the amount of CPU use is to use a short blocking read (see the timeout() functionalityin the curses library). Unfortunately, this has had some other side effects (like a screen running one char behind) due to (what I think) is a bug in curses. I'm tempted to implement a separate thread which does some kind of exponential-backoff poll on the keyboard, and provides the input back to the kgetch() routines in fos_os2.c(?). Hmm. This may need some more thought; I'll post back when I have more ideas. Or if you have some, that'd be cool. :) Wes --- Maximus/2 3.01* Origin: COMM Port OS/2 juge.com 204.89.247.1 (281) 980-9671 (1:106/2000) SEEN-BY: 633/267 270 @PATH: 106/2000 633/267 |
