What is it you are attempting to do?
Nothing very fancy, I'm afraid. I want to do something like WSAWaitForMultipleEvents() (with infinite timeout) Win32 API call sort of trick with select(). I want to set fd1 and fd2 for, say, read file descriptor while fd1 would be a socket (return value of a socket() call) to get the network events and fd2 would be in my control.
Or, int other words. I know select() returns when one of the file descriptors is set by a network event. The question is, may I set this file desriptor explicitly from another thread when the original thread blocks on select() ?
