question on gtk_main

[Jyothi <jyothi ncoretech com>]

Hi,

    I have to do some processing as soon as the gtk_main is entered . so
which event is used to indicate this??
If I run my application as background process and kill it , I should do
some fill updates before quiting the applicaton. How should I do this???

Thanks in Advance,
Jyothi.
