Martyn:
Thank you very much for your reply. Yes shortly after posting, i found out
that returning false was the right way to do things.
At this time things are working as I had designed, and intended... I am not
sure why things started working, but they are working so I am not going to
ask to many questions. Basically I just used a global variable to pass
information into my update_server_version function. I simply cant figure out
how to get the g_idle_add() function to pass in the argument without
mangling the data.
Personally I do not like using global variables as I have been taught that
they are inherently evil, but in this case (and also in the pthread_creat
case i have used in other programs) I can not seem to find a way to pass the
data into the thread being created without it somehow being mangled.
Any way, things are working for the time being, though it seems to be
running bandaged code.
Sincerely
Melvin Newman

Hi, you need to make sure that the data structure is allocated and valid
at the time that the idle callback is called. Perhaps you should do
something like:
g_idle_add(update_server_version, g_strdup (data.data));
Which means the string has memory allocated for it. Then in the your
callback, you can call g_free (data) to make sure the memory is freed up
when you are done with it.

Instead of using g_idle_remove_by_data() here, you should be able to
return FALSE in that function, for more information, see the
documentation for g_idle_add().
