[libvirt] PATCH 2/5:centralize exit paths in remote driver
Daniel P. Berrange
berrange at redhat.com
Tue Dec 9 12:16:00 UTC 2008
This patch merges all exit paths in the remote driver APIs so we more or
less always have a single exit path in every method. NB we don't quite
follow the HACKING guideline of naming cleanup paths 'cleanup', since
we will need two possible cleanup points in some methods. So I've got a
slightly different pattern
cleanup:
....release data we allocated, typically free'ing the XDR object
done:
return ret;
}
In the next patch, the 'done' label will also unlock the driver.
