libev

WARNING: This is limited to network sockets in Windows, and then only if embedded. It seems having a unified event driven system for timers/sockets/etc isn't going to work quite right.

libev is a cross-platform library for events. Events are a way to call functions when an interesting "event" happens, such as a file being written to, timer expiring, or a network packet being received on a network socket.

On Windows (therefore, MinGW), libev is only supported by embedding into a project.

Patch the source code

Version 3.9 has some small bugs in it's WIN32 support. See this thread.

These have been patched in the development version.

# define EV_WIN32_HANDLE_TO_FD(handle) _open_osfhandle (handle, 0)

Line 969:

return EV_FD_TO_WIN32_HANDLE (fd) != -1;

Line 1184:

ioctlsocket (EV_FD_TO_WIN32_HANDLE (fd), FIONBIO, &arg);
