From da129ab38c3fb6ed3de85ffb6f8938eb31130a53 Mon Sep 17 00:00:00 2001 From: Ryan Harrison Date: Tue, 1 Aug 2017 15:16:59 -0400 Subject: Replace raw value for constant error value in string operations Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around. The standard library for similar operations uses a npos constant. This CL implements FX_STRNPOS, and replaces usages of magic number checking. It also does some type cleanup along the way where it was obvious that FX_STRSIZE should be being used. Removing the magic numbers should make eventually changing FX_STRSIZE to be unsigned easier in the future.
