With Mac OS X 10.9, xdrproc_t is no longer defined as:
typedef bool_t (*xdrproc_t)(XDR *, ...);
but instead as:
typdef bool_t (*xdrproc_t)(XDR *, void *, unsigned int);
For reference, Linux systems typically define it as:
typedef bool_t (*xdrproc_t)(XDR *, void *, ...);
The rationale explained in the header is that using a vararg is incorrect and has a potential to change the ABI slightly do to compiler optimizations taken and the undefined behavior. They decided to specify the exact number of parameters and for compatibility with old code decided to make the signature require 3 arguments. The third argument is ignored for cases that its not used and its recommended to supply a 0. ---
This patch is another option to fix the issue seen on Mac OS X. The original is available here: https://www.redhat.com/archives/libvir-list/2013-October/msg01153.html -- Doug Goldstein
