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 ?
