tep_set_loglevel - Man Page
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);
Files
event-parse.h Header file to include in order to have access to the library APIs. -ltraceevent Linker switch to add when building a program that uses the library.
