NAME

6       tep_set_loglevel - Set log level of the library
7

SYNOPSIS

9       #include <event-parse.h>
10
11       enum tep_loglevel {
12               TEP_LOG_NONE = 0,
13               TEP_LOG_CRITICAL,
14               TEP_LOG_ERROR,
15               TEP_LOG_WARNING,
16               TEP_LOG_INFO,
17               TEP_LOG_DEBUG,
18               TEP_LOG_ALL
19       };
20
21       int tep_set_loglevel(enum tep_loglevel level);
22

DESCRIPTION

24       The tep_set_loglevel() function sets the level of the library logs that
25       will be printed on the console. Library log levels are:
26
27                   TEP_LOG_NONE - Do not print any logs.
28                   TEP_LOG_CRITICAL - Print critical logs, problem that may cause a crash.
29                   TEP_LOG_ERROR - Print error logs, problem that could break the main logic of an API.
30                   TEP_LOG_WARNING - Print warnings, problem that could limit the result of an API.
31                   TEP_LOG_INFO - Print information about normal execution of an API.
32                   TEP_LOG_DEBUG - Print debug information.
33                   TEP_LOG_ALL - Print logs from all levels.
34
35       Setting the log level to specific value means that logs from the
36       previous levels will be printed too. For example TEP_LOG_WARNING will
37       print any logs with severity TEP_LOG_WARNING, TEP_LOG_ERROR and
38       TEP_LOG_CRITICAL. The default log level is TEP_LOG_CRITICAL.

45           /* call libtraceevent APIs and observe any logs they produce */
46           ...
47           tep_set_loglevel(TEP_LOG_CRITICAL);
