The above code snippet registers the ``app_trace_string`` tracepoint to
trace library. Here, the ``my_tracepoint.h`` is the header file
However, it is recommended to have a similar name for a better naming
convention.
-The user must register the tracepoint before the ``rte_eal_init`` invocation.
-The user can use the ``RTE_INIT`` construction scheme to achieve this.

the user must use ``RTE_TRACE_POINT_FP`` instead of ``RTE_TRACE_POINT``.
``RTE_TRACE_POINT_FP`` is compiled out by default and it can be enabled using
