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,
|

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_.
