LIBTRACEEVENT(3) libtraceevent ManualLIBTRACEEVENT(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> voidtep_print_printk(struct tep_handle *tep); voidtep_print_funcs(struct tep_handle *tep); voidtep_set_test_filters(struct tep_handle *tep, int test_filters); voidtep_plugin_print_options(struct trace_seq *s);
Thetep_print_printk()function prints the printk string formats that were stored for this tracing session. Thetep argument is trace event parser context. Thetep_print_funcs()function prints the stored function name to address mapping for this tracing session. Thetep argument is trace event parser context. Thetep_set_test_filters()function sets a flag to test a filter string. If this flag is set, whentep_filter_add_filter_str()API as called, it will print the filter string instead of adding it. Thetep argument is trace event parser context. Thetest_filters argument is the test flag that will be set. Thetep_plugin_print_options()function writes a list of the registered plugin options intos.
