libtracecmd(3) ============= NAME ---- tracecmd_set_loglevel - Set log level of the library SYNOPSIS -------- [verse] -- *#include * 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 ------- [source,c] -- #include ... 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 ----- [verse] -- *trace-cmd.h* Header file to include in order to have access to the library APIs. *-ltracecmd* Linker switch to add when building a program that uses the library. -- SEE ALSO -------- _libtracefs(3)_, _libtraceevent(3)_, _trace-cmd(1)_ _trace-cmd.dat(5)_ AUTHOR ------ [verse] -- *Steven Rostedt* *Tzvetomir Stoyanov* -- REPORTING BUGS -------------- Report bugs to LICENSE ------- libtracecmd is Free Software licensed under the GNU LGPL 2.1 RESOURCES --------- https://git.kernel.org/pub/scm/utils/trace-cmd/trace-cmd.git/ COPYING ------- Copyright \(C) 2021 VMware, Inc.
