When are these g_io_channel_*() input conditions occuring ?

[Philippe Bertin <philippe bertin telenet be>]

Hello all,

This is a new thread, based upon a very recent thread in this list, and 
a some things I asked myself in the (recent) past when I programmed a 
g_io_channel watcher callback.

I used, for my GIOChannel, the condition G_IO_IN, in order to have my 
callback called whenever there was any input data available. Although I 
could imagine when one would possibly get any of both the G_IO_PRI (I 
guess the socket's O-O-B condition is triggering it ?) or G_IO_HUP 
conditions, still I had wondered when one would possibly get G_IO_NVAL ? 
Maybe that last one is only applicable in case of nonblocking operations ?

I must've missed some documentation ?

Kind regards,

PhB
