Waiting for the child process to finis

Hello,

I would like to  know when  application  launched  by my program  has 
finished its execution.

I'm using g_app_info_launch from GIO but it only allows me to launch 
application without giving any possibility to get a knowledge in a 
future when that application has finished.

Does any of the other gnome family libraries allows me to do this? Or I 
just need to use fork() and exec() functions?

Regards
