Apps using libvirt will often have code like
if (virXXXX() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Something failed: %s\n", err && err->message ? err->message : "unknown error"); return -1; }
Checking for a NULL error object or message leads to very verbose code. A virGetLastErrorMessage() helper from libvirt can simplify this to
if (virXXXX() < 0) { fprintf(stderr, "Something failed: %s\n", virGetLastErrorMessage()); return -1; }

ACK. Client-side only, so it doesn't need RPC support. Should we update examples/hellolibvirt/hellolibvirt.c to use it? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
