/* Any definitions using GPollFD or GPollFunc are primarily
 * for Unix and not guaranteed to be the compatible on all
 * operating systems on which GLib runs. Right now, the
 * GLib does use these functions on Win32 as well, but interprets
 * them in a fairly different way than on Unix. If you use
 * these definitions, you are should be prepared to recode
 * for different operating systems.
 *
 * Note that on systems with a working poll(2), that function is used
 * in place of g_poll(). Thus g_poll() must have the same signature as
 * poll(), meaning GPollFD must have the same layout as struct pollfd.
 *
 * On Win32, the fd in a GPollFD should be Win32 HANDLE (*not* a file
 * descriptor as provided by the C runtime) that can be used by
 * MsgWaitForMultipleObjects. This does *not* include file handles
 * from CreateFile, SOCKETs, nor pipe handles. (But you can use
 * WSAEventSelect to signal events when a SOCKET is readable).
 *
 * On Win32, fd can also be the special value G_WIN32_MSG_HANDLE to
 * indicate polling for messages.
 *
 * But note that G_WIN32_MSG_HANDLE GPollFDs should not be used by GDK
 * (GTK) programs, as GDK itself wants to read messages and convert them
 * to GDK events.
 *
 * So, unless you really know what you are doing, it's best not to try
 * to use the main loop polling stuff for your own needs on
 * Windows.
