Author: ian Date: Tue Jun 5 14:47:13 2018 New Revision: 334656 URL: https://svnweb.freebsd.org/changeset/base/334656 Log: Add vsnprintf() to libsa. Alpha-sort the printf prototypes in stand.h. I'm not sure why the v*printf() functions in libsa return void instead of int, but this maintains that convention for the new function.
