NAME top

       tep_set_loglevel - Set log level of the library

SYNOPSIS top

#include <event-parse.h>       enumtep_loglevel{               TEP_LOG_NONE = 0,               TEP_LOG_CRITICAL,               TEP_LOG_ERROR,               TEP_LOG_WARNING,               TEP_LOG_INFO,               TEP_LOG_DEBUG,               TEP_LOG_ALL       };       inttep_set_loglevel(enum tep_loglevellevel);

DESCRIPTION top

       Thetep_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 exampleTEP_LOG_WARNING       will print any logs with severityTEP_LOG_WARNING,TEP_LOG_ERROR       andTEP_LOG_CRITICAL. The default log level isTEP_LOG_CRITICAL.

EXAMPLE top

           #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);
