tep_print_printk, tep_print_funcs, tep_set_test_filters, tep_plugin_print_options - Print libtraceevent
Contents
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);
