Subject: [lttng-dev] Usage example of libbabeltrace (babeltrace2) to read CTF traces from a GUI
Date: Mon, 14 Jun 2021 16:00:47 -0400 (EDT)	[thread overview]
Message-ID: <1119833442.5505.1623700847146.JavaMail.zimbra@efficios.com> (raw)

Hi Philippe, Hi Jeremie,

Steven is interested to use libbabeltrace as a CTF trace reader in the KernelShark
project. It's a GUI which shows Linux kernel traces.

He notices that most of the documented usage examples of the libbabeltrace API
focus on use-cases where a custom trace format is converted into CTF.

I know that the babeltrace2 program is the main user of libbabeltrace at this
point, and that it reads CTF as source.

For using libbabeltrace as CTF reader for a GUI, what would be the best examples
to look at as starting point ? Perhaps the babeltrace2 binary, or just adapt a
smaller example program and change the custom trace format source to "ctf.fs" ?
Or anything else ?

Thanks,

Mathieu
