LIBTRACEEVENT(3) libtraceevent Manual LIBTRACEEVENT(3)
tep_set_loglevel - Set log level of the library
#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);
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.
#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);
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.
