NAME

       tracefs_set_loglevel - Set log level of the library

SYNOPSIS

       #include <tracefs.h>

       int tracefs_set_loglevel(enum tep_loglevel level);

DESCRIPTION

       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

           #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);
