NAME         top

       tracefs_set_loglevel - Set log level of the library

SYNOPSIS         top

       #include <tracefs.h>

       int tracefs_set_loglevel(enum tep_loglevel level);

DESCRIPTION         top

       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.

EXAMPLE         top

           #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);
