Hello, I have installed the latest version of cygwin on XP and it works fine. I'm trying to write a small C application that reads data from a Microphone. Another application is attempting to write data to the sound card to be played. Does anyone know how to open a connection (file descriptor) to the microphone? --Eli -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
