libtraceevent(3)
================
NAME
----
tep_print_printk, tep_print_funcs, tep_set_test_filters, tep_plugin_print_options -
Print libtraceevent internal information.
SYNOPSIS
--------
[verse]
--
*#include <event-parse.h>*
*#include <trace-seq.h>*
void *tep_print_printk*(struct tep_handle pass:[*]tep);
void *tep_print_funcs*(struct tep_handle pass:[*]tep);
void *tep_set_test_filters*(struct tep_handle pass:[*]tep, int test_filters);
void *tep_plugin_print_options*(struct trace_seq pass:[*]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
-------
[source,c]
--
#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);
