Okay. This was helpful.

I will be storing the event stream in a file and I will pass metadata file
to babeltrace in order to read the CTF.

 I want to make babeltrace read my metadata file and event stream stored in
a file. How does babeltrace read an arbitrary CTF session(CTF+event stream)?

What should be the file format to store the event stream? I will use
fwrite() to store the events.
