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;
}

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
