Subject: [PATCH 10/28] Don't shadow global function names
Date: Wed, 28 Sep 2022 14:33:21 +1000	[thread overview]
Message-ID: <20220928043339.613538-11-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20220928043339.613538-1-david@gibson.dropbear.id.au>

[-- Attachment #1: Type: text/plain, Size: 1427 bytes --]

cppcheck points out that qrap's main shadows the global err() function with
a local.  Rename it to rc to avoid the clash.
