NAME

       tep_set_loglevel - Set log level of the library

SYNOPSIS

       #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:

                   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

           #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);
