re hello
perhaps there is a link with the script being called..
as there is a function which use stdout:
here it is
--------------------------------------------
def erreur_ccm(cmd):
try:
child_stdin, child_stdout, child_stderr =os.popen3(cmd)
stderr=child_stderr.read()
stdout=child_stdout.read()
if stderr == "":
retour = stdout
else :
retour = 0
except OSError, e:
child_stdin.close()
child_stdout.close()
child_stderr.close()
return retour
