Eric (cecas...@aol.com) sent me the following earlier today in response to
another discussion thread I started a few days ago re: GSubProcess:
I put together a test example of GSubprocess. ...
https://github.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/Pipes/gnuplot5.c
In an amazing bit of coincidence, Eric's example contains the following
bit of code which would seem to have some bearing on this file descriptor
watch discussion thread:
GSource *source=g_pollable_input_stream_create_source((GPollableInputStream*)err_stream,
NULL);
g_source_attach(source, NULL);
g_source_set_callback(source, (GSourceFunc)read_err, NULL, NULL);
Could this be yet another way to skin my cat? Perhaps better than the
GIOChannel, if not the g_source_add_unix_fd() solution? Looks like I could
create my own GInputStream with
GInputStream *gis= g_unix_input_stream_new(mypipefd, FALSE);
and then use that stream (which should also be a GPollableInputStream,
yes?) in the call to g_pollable_input_stream_create_source(). I had not
intended to use stream (i.e., buffered) i/o, but there's probably no harm
in doing so. This seems like a perspiration-free way to create the GSource
I need.
Thanks doubly, Eric!
Roger
