* tests/gio-test.c (main): Fix the Win32-only code to use current
API, g_io_channel_win32_make_pollfd() and g_io_channel_win32_poll().
Mon Aug 21 14:46:23 2000 Owen Taylor <otaylor@redhat.com>
* tests/gio-test.c: Fix a couple of trivial bugs that
were causing warnings.

* glib.h: Use C99 varargs macros where possible
(check __STDC_VERSION__), otherwise, on gcc, use an alternate
form of gcc varargs which is more likely
to be supported going forward. (Based on some code
from Raja Harinath)

* tests/gio-test.c (shutdown_source): New function, that calls
g_source_remove(). Check return value of g_source_remove(), and
decrement running subprocess counter only if g_source_remove()
actually did remove the source.
(recv_message): Call shutdown_source() on EOF condition. Return
FALSE on G_IO_HUP and G_IO_ERR condition. Fix printf format typo.

* giowin32.c: Compile in the debugging code all the time, but only
output debug messages if told so. Add (unadvertised) function to
turn on/off debug messages for a channel.
(buffer_read): Don't loop. It is expected behaviour to return a
short read occasionally, for instance when reading from
pipes. It's the calling code that should loop if it *knows* how
much the writer has written.
* tests/gio-test.c: Correct the program's name in the output.
(recv_message): Loop calling g_io_channel_read() (in a new
function read_all()) until we have all the bytes we want (that we
know the writer has written/will write).

Finally, a new and improved IO Channel and condition watch
implementation for Win32. 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.
