Don Lewis 866046f5a6 Add MSG_NBIO flag option to soreceive() and sosend() that causes ... them to behave the same as if the SS_NBIO socket flag had been set for this call. The SS_NBIO flag for ordinary sockets is set by fcntl(fd, F_SETFL, O_NONBLOCK). Pass the MSG_NBIO flag to the soreceive() and sosend() calls in fifo_read() and fifo_write() instead of frobbing the SS_NBIO flag on the underlying socket for each I/O operation. The O_NONBLOCK flag is a property of the descriptor, and unlike ordinary sockets, fifos may be referenced by multiple descriptors.		2004-06-01 01:18:51 +00:00
