LIBTRACEEVENT(3) libtraceevent Manual LIBTRACEEVENT(3)
tep_print_printk, tep_print_funcs, tep_set_test_filters,
tep_plugin_print_options - Print libtraceevent internal
information.
#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);
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.
