exit status from a pipe

[user]

How can I get the exit status from a "popen2" pipe?
For example, from

child_stdout, child_stdin, child_stderr = popen2.popen3(command)

how can I tell what the exit status it?
Want to find out if a command actuall succeeded.

Straight from the online manual:

The only way to retrieve the return codes for the child processes is by
using the poll() or wait() methods on the Popen3 and Popen4 classes;
these are only available on Unix. This information is not available when
using the popen2(), popen3(), and popen4() functions, or the equivalent
functions in the os module.
Most if not all of the answers to such question are available in the
(very good) Python documentation.
