From 473828ca6aef18c574b8665ae484513e5592af03 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Thu, 29 Oct 2020 23:54:17 -0400 Subject: command: Add command_decode_ptr() helper Add a helper function to convert from a string buffer passed in the args[] parameter to an actual pointer. This avoids all the callers needing to perfrom pointer manipulation.
