# tep\_print\_printk(3)

Print libtraceevent internal information.

## NAME

tep\_print\_printk, tep\_print\_funcs, tep\_set\_test\_filters, tep\_plugin\_print\_options - Print libtraceevent internal information.

## SYNOPSIS

```
#include <event-parse.h>
#include <trace-seq.h>
void tep_print_printk(struct tep_handle *tep);
void tep_print_funcs(struct tep_handle *tep);
void tep_set_test_filters(struct tep_handle *tep, int test_filters);
void tep_plugin_print_options(struct trace_seq *s);
```

## DESCRIPTION

The **tep\_print\_printk()** function prints the printk string formats that were stored for this tracing session. The *tep* argument is trace event parser context.

The **tep\_print\_funcs()** function prints the stored function name to address mapping for this tracing session. The *tep* argument is trace event parser context.

The **tep\_set\_test\_filters()** function sets a flag to test a filter string. If this flag is set, when **tep\_filter\_add\_filter\_str()** API as called, it will print the filter string instead of adding it. The *tep* argument is trace event parser context. The *test\_filters* argument is the test flag that will be set.

The **tep\_plugin\_print\_options()** function writes a list of the registered plugin options into *s*.

## EXAMPLE

```
#include <event-parse.h>
#include <trace-seq.h>
...
struct tep_handle *tep = tep_alloc();
...
        tep_print_printk(tep);
...
        tep_print_funcs(tep);
...
struct tep_event_filter *filter = tep_filter_alloc(tep);
        tep_set_test_filters(tep, 1);
        tep_filter_add_filter_str(filter, "sched/sched_wakeup:target_cpu==1");
        tep_set_test_filters(tep, 0);
        tep_filter_free(filter);
...
struct trace_seq seq;
trace_seq_init(&seq);
        tep_plugin_print_options(&s);
...
```
