Hello !
I've got a question, it can seems stupid to you but it's really a problem for me.
What's the function, how to, quit a program ? 
and if I have 2 or more process in my program how can I stop all the program ?
thanks for your responses |

Please define "the program"...
if you by "the program" mean the virtual machine then try:
init:stop/1 <- Graceful
erlang:halt/0 <- Kill it
q/0 <- Graceful (from shell only)
In order to shutdown everything properly you should learn about how to create applications (http://www.erlang.org/doc/design_principles/applications.html#7) then you should learn about releases (http://www.erlang.org/doc/design_principles/release_structure.html#10) then you can read about how to stop and start releases properly using OTP.
If you don't want all this then you can just make 1 process which starts other processes and then send them all a message when you call mymodule:stop().
