* The event loop functionality GMain has extensively been revised to 
  support multiple separate main loops in separate threads. All sources
  (timeouts, idle functions, etc.) are associated with a GMainContext.

  Compatibility functions exist so that most application code dealing with
  the main loop will continue to work. However, code that creates
  new custom types of sources will require modification.

  The main changes here are:

   - Sources are now exposed as GSource *, rather than simply as numeric
     IDS.

   - New types of sources are created by structure "derivation" from GSource,
     so the source_data parameter to the GSource vfuncs has been
     replaced with a GSource *.

   - Sources are first created, then later added to a specific GMainContext

   - Dispatching has been modified so both the callback and data are passed
     in to the ->dispatch() vfunc.

  To go along with this change, the vtable for GIOChannel has changed and
  add_watch() has been replaced by create_watch().
Major change in API for creating sources to handle multiple main loops Tue Dec 5 12:23:04 2000 Owen Taylor <otaylor@redhat.com> * gmain.[hc]: Major change in API for creating sources to handle multiple main loops (GMainContext ). GSources are now exposed as GSource and implemented with structure derivation. * giochannel.[ch]: Changed vtable for GIOChannel to correspond to the new mainloop API, add g_io_channel_create_watch(). * gtypes.h: Move GTimeVal here. * gthread.h: Remove gmain.h include to avoid circularity. * giounix.c: Update for new GMain API. * giowin32.c: Update for new GMain API. (No check for proper compilation or working.) * timeloop.c timeloop-basic.c: A benchmarking program for the main loop comparing the main loop against a hand-written (timeloop-basic.c) variant. * tests/mainloop-test.c: New torture test of mainloop. * docs/Changes-2.0.txt: Started. Added text about changes to GMain. * gmain.c (g_main_add_poll_unlocked): Initial fd->revents to zero.
