Signals are represented, in the kernel and in the API, as bits in fixed-size bitmaps. POSIX real-time signals, if we implemented them, would at least give you the opportunity to queue signals, with unique ancillary data attached to each instance. We have all the mechanism to do this in the user-kernel interface; it's just not implemented in the kernel. -GAWollman _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
