НАЗВАНИЕ

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

СИНТАКСИС

       #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);

ОПИСАНИЕ

       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.
