When doing IPC or networking programs, there are ofter file descriptors that are to be polled always for reading, but for writing, only when there is some data pending. I do not see elegant ways to do that. It is possible to remove the read only watch, and add the read/write watch when the buffer is filled, and do the contrary when it is emptied, but this is lot of bookkeeping for nothing. It may be possible to use two GIOChannels, and add/remove a write only watch on the second, while there is always a read only watch on the first, but it a bit wastful, and I do not know if it is possible to have the same fd for two watchs. It is possible to redefine watch functions using g_source_* (what I have done yesterday). Perharps a function like g_io_channel_set_watch_condition could be useful for that.
