10:59 p.m.
All uses of virLibNetworkError passed __FUNCTION__ as the info string;
avoid the duplication by factoring it into a macro which can contain
additional information (namely, the line number). The resulting
error messages differ in the attributed location (now pointing to
the caller rather than the helper), but the rest of the error
text is unchanged.
* src/libvirt.c (virLibNetworkError): Convert to macro, and drop
extra parameter. All callers simplified.
(virLibNetworkErrorHelper): Refactor function to take new parameters.
---
If this type of cleanup is desirable, I can trim the 600+ other
uses of __FUNCTION__ out of libvirt.c.
