NAME

6       tep_print_printk, tep_print_funcs, tep_set_test_filters,
7       tep_plugin_print_options - Print libtraceevent internal information.

SYNOPSIS

10       #include <event-parse.h>
11       #include <trace-seq.h>
12
13       void tep_print_printk(struct tep_handle *tep);
14       void tep_print_funcs(struct tep_handle *tep);
15       void tep_set_test_filters(struct tep_handle *tep, int test_filters);
16       void tep_plugin_print_options(struct trace_seq *s);
17

DESCRIPTION

19       The tep_print_printk() function prints the printk string formats that
20       were stored for this tracing session. The tep argument is trace event
21       parser context.
22
23       The tep_print_funcs() function prints the stored function name to
24       address mapping for this tracing session. The tep argument is trace
25       event parser context.
26
27       The tep_set_test_filters() function sets a flag to test a filter
28       string. If this flag is set, when tep_filter_add_filter_str() API as
29       called, it will print the filter string instead of adding it. The tep
30       argument is trace event parser context. The test_filters argument is
31       the test flag that will be set.
32
33       The tep_plugin_print_options() function writes a list of the registered
34       plugin options into s.
