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); ...
