       The tracefs_set_loglevel() function sets the level of the library logs that will be printed on the
       console. See libtraceevent(3) for detailed description of the log levels. Setting the log level to
       specific value means that logs from the previous levels will be printed too. For example TEP_LOG_WARNING
       will print any logs with severity TEP_LOG_WARNING, TEP_LOG_ERROR and TEP_LOG_CRITICAL. The default log
       level is TEP_LOG_CRITICAL. When a new level is set, it is also propagated to the libtraceevent.

           #include <tracefs.h>

           tracefs_set_loglevel(TEP_LOG_ALL);
           ...
           /* call libtracefs or libtraceevent APIs and observe any logs they produce */
           ...
           tracefs_set_loglevel(TEP_LOG_CRITICAL);

tracefs.h
                   Header file to include in order to have access to the library APIs.
           -ltracefs
                   Linker switch to add when building a program that uses the library.
