Message-ID: <1995Mar20.110536.3047@sserve.cc.adfa.oz.au> Organization: Australian Defence Force Academy, Canberra, Australia Date: Mon, 20 Mar 1995 11:05:36 GMT I am using "select" to wait for input on a number of UDP sockets. "Select" returns normally, usually with the value of one when a datagram arrives but the mask of read file descriptors passed to select are returned unchanged. Consequently, I cannot determine which file descriptor I can read from. I have been known to write incorrect code but perhaps "select" is misbehaving (using FreeBSD 1.1.5.1)?? Any help would be greatly appreciated.
