Subject: [PATCH 2/5] perf stat: Refactor the code to strip csv output with ltrim()
Date: Fri, 7 Apr 2017 23:24:18 +0900 [thread overview]
Message-ID: <1491575061-704-3-git-send-email-treeze.taeung@gmail.com> (raw)
In-Reply-To: <1491575061-704-1-git-send-email-treeze.taeung@gmail.com>
To strip csv output, use ltrim() instead of
just while loop and isspace() at print_metric_{only}_csv().
