[Ace-users] howto return immediately from poll ?

compiler: vs.net 2003, gcc 3.3.3

in my app, I call poll to wait on a file descriptor (in fact, it is an
inotify handler). to achieve, I wait infinitely.  My question is :
How to notify the poll function to return ?  I close the file
descriptor from another thread, but it still
blocks. Can I poll on an event handler, so when needed, I can signal
the event (so the poll function returns).
thanks in advance
