Okay. Thanks for the clarification. The small example that I showed you
where CTF data was printed in text format using babeltrace. It requires
LTTng-UST. We can't use it because you had already mentioned that there is
a license problem with it.

With LTTng-UST I was able to define tracepoint provider package and
tracepoints in the program. You can follow this link in case if you wanna
have a look at it again.
https://lttng.org/docs/v2.10/#doc-tracing-your-own-user-application

Without the help of LTTng-UST how we will be able to define tracepoints in
the program?
