[lttng-dev] [Patch LTTng-ust 3/7] Add an example using CTF named enumerations
Geneviève Bastien

Fri Jan 24 15:04:41 EST 2014
A new test example is introduced in tests/ctf-metadata. This test application
will be used to test the support of named CTF metadata. For now, it contains
two tracepoints that use a named enumeration.
