NAME
----
tep_set_loglevel - Set log level of the library

SYNOPSIS
--------
[verse]
--
*#include <event-parse.h>*

enum *tep_loglevel* {
	TEP_LOG_NONE = 0,
	TEP_LOG_CRITICAL,
	TEP_LOG_ERROR,
	TEP_LOG_WARNING,
	TEP_LOG_INFO,
	TEP_LOG_DEBUG,
	TEP_LOG_ALL
};

int *tep_set_loglevel*(enum tep_loglevel _level_);

--
DESCRIPTION
-----------
The *tep_set_loglevel()* function sets the level of the library logs that will be printed
on the console. Library log levels are:
[verse]
--
	_TEP_LOG_NONE_ - Do not print any logs.
	_TEP_LOG_CRITICAL_ - Print critical logs, problem that may cause a crash.
	_TEP_LOG_ERROR_ - Print error logs, problem that could break the main logic of an API.
	_TEP_LOG_WARNING_ - Print warnings, problem that could limit the result of an API.
	_TEP_LOG_INFO_ - Print information about normal execution of an API.
	_TEP_LOG_DEBUG_ - Print debug information.
	_TEP_LOG_ALL_ - Print logs from all 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_.


EXAMPLE
-------
[source,c]
--
#include <event-parse.h>

tep_set_loglevel(TEP_LOG_ALL);
...
/* call libtraceevent APIs and observe any logs they produce */
...
tep_set_loglevel(TEP_LOG_CRITICAL);
--
