I'm trying to do some work with X, and I'd like to get a SIGIO signal whenever there's data available on the X socket. The documentation for sigvec indicates that (a) there is such a signal, and (b) I should read the documentation for fcntl to find out how it works. Reading this documentation indicates that I can use F_SETOWN to indicate where to send the SIGIO signal, but doesn't tell me how to get one in the first place. There doesn't seem to be an FASYNC flag, a la Sun, so I am stymied. How does one use this signal? _MelloN_
