From 830bc28c45091990ad7f53e3fdea2f1166b5901d Mon Sep 17 00:00:00 2001 From: Manav Rathi Date: Fri, 6 Mar 2015 09:04:10 +0530 Subject: [PATCH] FS-7352: Document how to use switch_core_set_variable to delete variables I had to scan through the source of the function to verify that this is the indeed the actual behaviour, and that NULL is a valid argument.
