From 81a9aa60a193f1181149b69920930e15c4e34059 Mon Sep 17 00:00:00 2001 From: Kjetil Barvik Date: Mon, 9 Feb 2009 21:54:08 +0100 Subject: create_directories(): remove some memcpy() and strchr() calls Remove the call to memcpy() and strchr() for each path component tested, and instead add each path component as we go forward inside the while-loop.
