| libtracefs(3) |
| ============= |
| |
| NAME |
| ---- |
| tracefs_set_loglevel - Set log level of the library |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| -- |
| *#include <tracefs.h>* |
| |
| int *tracefs_set_loglevel*(enum tep_loglevel _level_); |
| -- |
| |
| DESCRIPTION |
| ----------- |
| The *tracefs_set_loglevel()* function sets the level of the library logs that will be printed on |
| the console. See _libtraceevent(3)_ for detailed description of the log 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_. When a new level is set, it is |
| also propagated to the libtraceevent. |
| |
| EXAMPLE |
| ------- |
| [source,c] |
| -- |
| #include <tracefs.h> |
| |
| tracefs_set_loglevel(TEP_LOG_ALL); |
| ... |
| /* call libtracefs or libtraceevent APIs and observe any logs they produce */ |
| ... |
| tracefs_set_loglevel(TEP_LOG_CRITICAL); |
