Hi Emmanuele,
Thanks for the additional documentation references! They were generally
informative, although I think the one you mentioned as being apropos of my
particular case was actually designed to be used for a source specifically
other than file descriptors -- it was useful nonetheless,

Thanks for all the further explication, Chris!
The problem is that the main loop would enter a busy loop. Well, maybe
a 'busy-ish' loop. If you call up g_idle_add() with a repeating
callback (one which returns TRUE) which does nothing except examine a
non-blocking select(), you will end up w

Hi Roger,
I put together a test example of GSubprocess. It starts Gnuplot, sets up
the pipes and callbacks, and then when Gnuplot is done it opens the
graph in an image widget. The GSubprocess will take care of the file
descripters for you. ...

I am specifically interested in the number of the monitor, which is
returned by gdk_screen_get_monitor_at_window. However, its advertised
replacement gdk_display_get_monitor_at_window only returns the pointer
to the monitor.
My try would be:
