How to run a C program and get output of the program using Twisted Python

Question

I have a Python Bot written using Twisted framework and I have a C program that outputs certain text. How would I be able to run have Twisted run the C program using a command, collect the output, then print the output back to me?

Answer 1

The easiest way is getProcessOutput :

from twisted.internet.utils import getProcessOutput
df = getProcessOutput('ls', args=('/home','-lah'))
df.addCallback( printOutput )

Also see http://twistedmatrix.com/documents/current/core/howto/process.html in case you need something more complex.
