Proper use of g_main_context_iteration

[Jacques Pelletier <jpelletier ieee org>]

Hi,

I'm using a separate thread for accepting clients on a socket server.
In this thread, the g_main_context_iteration is called to update the GUI.

Do I need to use g_main_context_acquire and/or g_main_context_release?

Apart from the code and the reference manuals, there's not much infos 
about the proper use of these functions.
What are these for? Where can I get a more detailled description of 
these functions?

Thanks!

JP
