NAME
       tracecmd_set_loglevel - Set log level of the library

SYNOPSIS
       #include <trace-cmd.h>

       int tracecmd_set_loglevel(enum tep_loglevel level);

DESCRIPTION
       The tracecmd_set_loglevel() function sets the level of the library logs
       that will be printed on the console. See libtraceevent(3) for detailed
       desciription 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 libtracefs and libtraceevent.

EXAMPLE
           #include <trace-cmd.h>
           ...
           tracecmd_set_loglevel(TEP_LOG_ALL);
           ...
           /* call libtracecmd, libtracefs or libtraceevent APIs and observe any logs they produce */
           ...
           tracecmd_set_loglevel(TEP_LOG_CRITICAL);

FILES
