Author: ed Date: Thu Jul 28 16:02:30 2016 New Revision: 303449 URL: https://svnweb.freebsd.org/changeset/base/303449
Log: Clean up use of basename() and dirname(). Pull copies of the input pathname string before calling basename() and dirname() to make this comply to POSIX. Free these copies at the end of this function. While there, remove the duplication of the 's' -> 'logfname' string. There is no need for this.
