From: root@jacob.remcomp.fr (root) Subject: Re: how to do a timeout in getchar 9 Mar 1998 05:06:04 -0800 Message-ID: References: Content-Type: text To: cgf@bbc.com Cc: gnu-win32@cygnus.com You can implement a version of getchar that does a non blocking read operation by opening the file (in this case stdin) with the FILE_FLAG_OVERLAPPED. In that case the read returns immediately. You could then loop waiting for a signal, or other event that would stop the loop, or just a character read. Another method is to use PeekConsoleInput, in this case you get mouse events, menu events, focus events, what have you. Yet another method is the age old _kbhit method: Read only if there is keyboard input available. This method works only with the keyboard. You can't use it with a redirected stdin. All those methods can be used to write a version of getchar that looks after signals, like non-defined signals under Win32: SIGALRM is one of those. Since this has only sense if you want Unix-like behaviour, I thought it should be the job of cygnus to emulate that. -- Jacob Navia Logiciels/Informatique 41 rue Maurice Ravel Tel 01 48.23.51.44 93430 Villetaneuse Fax 01 48.23.95.39 France - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
