Based on code provided by Craig Setera. + + When watching file descriptors, for which there is no select() + like functionality on Win32 that would work on all Win32 platforms + for all types of file descriptors (including anonymous pipes), we + start a new thread that blocks while trying to read from the file + descriptor. When the read returns, a Win32 Event is signalled that + the polling routine eventually notices. Meanwhile, the data being + read is stored in a circular buffer, from where the IO channel's + read() method picks it up. + + If the buffer fills up the reading thread has to wait for space + becoming available. For this another Win32 Event is used. The IO + Channel's read() method signals this when it has read some data + out of the buffer. + + The separate reader thread(s), and the circular buffer(s) with + associated events mean lots of possibilities for fun parallellism + errors. But it seems to work OK, i.e. GIMP runs. + + * gmain.c: Small changes to the Win32 polling function. + (g_main_win32_get_poll_func): New function. Perhaps it would be a + good idea to provide this on all platforms. + + * giowin32.c: The bulk of the new implementation. + (g_io_channel_win32_wait_for_condition): New function. To be used + where on Unix one does a select() on the channel's fd, like + libgimp's gimp_extension_process(). Could be provided on all + platforms. + + * glib.h: Update documentation for IO Channels on Win32. Remove + the declarations for the as of now obsolete old functions related + to IO Channels for pipes with "wakeup" messages. + + * glib.def: Some new functions. + + * tests/gio-test.c: New file, to test GIOChannel and main loop. + + * tests/Makefile.am + * tests/makefile.mingw.in: Add it. + Thu Jul 27 05:15:11 2000 Tim Janik <timj@gtk.org> * gstrfuncs.c (g_strlcpy, g_strlcat): completed tor's fix |
