It's an SVR4-emulator running on NetBSD, or a NetBSD-emulator on a generic SVR4? Well, I don't know, are there any BSD-ish Unices which has poll, because it has ``select'' at all, and as in Stevens: Advanced Programming in the UNIX Environment: pg 400: The SVR4 poll function is similar to select, but the programming interface is different. pg 396: The poll function is provided only by SVR4. SVR4 actually implements select using poll. (Well, in the next paragraph, he said, that poll was in SVR3, too - and yes, it was.) --> Maybe you can implement poll with select, too. (It's not Stevens, it's me.) And I think, if it's an SVR4-emulator on NetBSD, they (the NBSD team) made such emulation of poll, with select. Bye, Gabor
