catch logout/SIGHUP

[Jochen Baier <Jochen.Baier@xxxxxxxxxxxxxxxxxxxxx>]

hi,

i wonder what is the right procedure to do some cleanup if the user 
logout from session
and the program is still alive. ("Save file before exit" etc)

I thought "system (SIGHUP,...)" is the right way, but i didnt find this 
function in code from gedit, anjuta etc.. so what is  the right way to 
do this ?

thanks jochen
