Re: [libvirt] [PATCH 1/3] Add a virGetLastErrorMessage() function

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; 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; } Signed-off-by: Daniel P.
