Subject: [PATCH v6 06/45] trace-cmd: Add APIs for library initialization and free
Date: Mon, 14 Jun 2021 10:49:50 +0300	[thread overview]
Message-ID: <20210614075029.598048-7-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210614075029.598048-1-tz.stoyanov@gmail.com>

The trace-cmd library has no APIs for initialization and free of the
whole library. Added these new APIs:
 tracecmd_lib_init()
 tracecmd_lib_free()
and call them in trace-cmd main function.
