os.spawn

[Donn Cave]

Quoth syt at pegasus.logilab.fr (Sylvain Thenault):

| how can I do for knowing what happend when I do an os.spawnv()
|
| for example, if i do
|
| import os
| os.spawnv(P_WAIT, '/bin/echo', 'this is a spawn test')
|
| I can't see anything, and don't know what have been made...

Normal return from os.spawnv should be 0.  Anything else indicates
failure.

   >>> print os.spawnv.__doc__
   spawnv(mode, file, args) -> integer

   Execute file with arguments from args in a subprocess.

Args here should be a tuple or list like sys.argv:
   os.spawnv(os.P_WAIT, '/bin/echo', ('echo', 'this is a spawn test'))
