@brief Common Trace Format Intermediate Representation.
The Common Trace Format Intermediate Representation,
or CTF IR, is the representation of the
CTF model within Babeltrace.
As with any Babeltrace object, all the CTF IR objects have
reference
counts. See \ref refs to learn more about the reference counting
management of Babeltrace objects.
When the documentation says that a given
\link ctfirfieldtypes CTF IR field type\endlink must be
equivalent to another one, it means that
bt_field_type_compare() \em must return 0.
