Subject: [PATCH v5 29/40] trace-cmd library: Make tracecmd_copy_headers() to work with output handler
Date: Thu, 10 Jun 2021 14:34:15 +0300 [thread overview]
Message-ID: <20210610113426.257931-30-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210610113426.257931-1-tz.stoyanov@gmail.com>
When copying headers between two trace files, use output handler context
instead of just a fd. Using output handler will allow to use file
compression, if needed.
This change fixes "trace-cmd split" command to work with trace files v7.
