Looking at the glib source here:
glib/giochannel.c
glib/giochannel.h
glib/giounix.c
You can see that, at least on a *nix machine, g_io_channel_read_chars()
calls the c library read() on a file descriptor in the GIOChannel
struct. The segment:

Thanks for your precisions on where this difference comes from :)
I guess g_io_channel_set_flags(_channel, G_IO_FLAG_NONBLOCK, NULL); is
good for switching to non-blocking mode.
A question arises, though: is it possible that the channel will recieve the
last of the data between the
time g_io
Callbacks on a GIOChannel (as described) are re-entrant!. I know since i
have hit this problem. Essentially you must read what you can. If its a
socket you would have soimething like
bytes_read = recv( fd, ( void * ) ( &buffer[
current_byte ] ), expected_size );

Hi,
you never know how much readable data is available until you read it, you
are only ever guaranteed to have one byte of data available for reading
anyway.
In my opinion, the channel should _always_ know how much data is available,
how can it tell that there is nothing there?... Plus, it can

Hi,
I need to read a large amount of data from a GIOChannel (200K, over
the internet).
So far, I use the gnet library to create the
socket, and then I use the GIOChannel to integrate the read/writing
into the program's loop (a
GTK application)
I use g_io_add_watch(_channel, G_IO_IN, &(_imageDat
