Re: [Vala] problem using sleep

[Arkadi Viner <arkashkin gmail com>]

I have a small question about this code:

If I add some code below your example would it be executed before
"Process.spawn_command_line_async" ? I mean, the program will go on and only
"Process.spawn_command_line_ async" is delayed  ?

If so, how can I delay the whole program ?

Sorry to interrupt and thanks...
