Look at the definition of CHECK_ERROR macro, used here: http://hg.et.redhat.com/applications/virt/applications/virt-top--devel?f=... (eg line 63) and defined here: http://hg.et.redhat.com/applications/virt/applications/virt-top--devel?f=... (line 45) and the _raise_virterror function which gets the virterror defined here: http://hg.et.redhat.com/applications/virt/applications/virt-top--devel?f=... (line 66) errp = conn ? virConnGetLastError (conn) : virGetLastError (); Note that actually copying the virterror may not be such a good idea. The lifetime of that structure and the strings / pointers contained within it is a little bit undefined, and the virCopy* functions don't do a deep copy IIRC. So you should take copies of anything you need yourself, and make sure you don't refer to the conn/dom/net structure fields if you can possibly avoid it.
