Subject: [PATCH] perf target: Ignore return value of strerror_r() explicitly
Date: Mon, 2 Jul 2012 15:20:14 +0900 [thread overview]
Message-ID: <1341210014-10113-1-git-send-email-namhyung@kernel.org> (raw)
From: Namhyung Kim <namhyung.kim@lge.com>
Since glibc 2.16 added the warn_unused_result (wur) attribute
to the function, we should check the return value or ignore it
explicitly.
