Signals?

In Linux, I have created a signal handler to handle the SIGUSR1 signal.

How can I do something equivalent in Windows (this is a console app)?

Thank you!

Windows doesn't have signals the way Linux does. You need to either use a library that simulates Unix style signals on Windows (cygwin does this I think), or move your application to an event based implementation instead of a signal based implementation.

Like what bithub said. Windows has events, messages, and mutexes. If you're interested look up CreateEvent(), SignalEvent(), and ResetEvent() on MSDN.

edit: Sorry if those aren't the exact function names, but it'll get you there.

signal() is an C89 standard call -- yes, really -- and Windows does support it. It probably doesn't have the SIGUSR1 signal, though.

I didn't say Windows doesn't support signals. I said that they do not work the same as in Linux. For instance, SIGUSR1 does not exist. Also you get little gems like this from MSDN:

Note SIGINT is not supported for any Win32 application, including Windows 98/Me and Windows NT/2000/XP.

Writing a Windows application that uses signals is just asking for trouble.
