I would strongly advise you NOT to use this API as we're about to
deprecate it in a few weeks when Babeltrace 2.0 is released. A whole new
API based on reference counts will be available when it's released and
you will be able to develop a filter plugin which can be inserted in a
graph of connected components where a stream of events and other
notifications flow.

In the meantime you can use the Python bindings (this API will remain
maintained) to achieve what you want.
