Proper way to handle errors from python restorecon binding?

[brianjmurrell]

It's not clear to me in which ways the restorecon() python binding can return an error/failure?

Can it raise an exception or does it always simply report errors in it's return code? I.e. I need to do:

rc = selinux.restorecon(path)
if rc != 0:
    [error handling]

And/or do I need a try/except block around restorecon() as something below it could raise an exception?

I have seen reference to code that calls it as such:

try:
  selinux.restorecon(path)
except selinux.SELinuxError:
  [error handling]
