* glib.h, galloca.h, garray.h, gasyncqueue.h, gbacktrace.h,
gcache.h, gcompletion.h, gconvert.h, gdataset.h, gdate.h, ghash.h,
ghook.h, giochannel.h, glist.h , gmacros.h, gmain.h, gmem.h,
gmessages.h, gnode.h, gprimes.h, gquark.h, gqueue.h, grand.h,
grel.h, gscanner.h, gslist.h, gstrfuncs.h, gstring.h, gthread.h,
gthreadpool.h, gtimer.h, gtree.h, gtypes.h, gutils.h: Split glib.h
into many header files mostly according to the resp. *.c-files.
* gmacros.h: Added G_BEGIN_DECLS and G_END_DECLS to mean: 'in case
of C++: extern "C" { ... }' analogous to glibc __BEGIN_DECLS and
__END_DECLS.
* configure.in, gerror.h, gfileutils.h, gshell.h, gspawn.h,
gunicode.h, : Changed guard-macro names to something more
consistent.
* configure.in, *.h: Use G_BEGIN_DECLS and G_END_DECLS.

/* GPollFD
|
|
*
|
|
* System-specific IO and main loop calls
|
|
*
|
|
* 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. These message queue GPollFDs should
|
|
* be added with the g_main_poll_win32_msg_add function.
|
|
*
|
|
* 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
|
|
* Win32. It's really only written for the GIMP's needs so
|
|
* far.
