| 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_. |

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