From 16c970d40e6c19dde705bad4751bab1a3a4f3a0d Mon Sep 17 00:00:00 2001 From: Oliver Hartkopp Date: Mon, 16 Sep 2013 09:08:56 +0200 Subject: [PATCH] slcand: silence warning about set but unused variable The dummyFile pointer was only needed to redirect stdxxx streams but it's content was never used. Re-use the pFile pointer for this reason which is unused at that point to silent the compiler warning about the set and unused dummyFile variable.
