.SH "NAME"
tep_print_printk, tep_print_funcs, tep_set_test_filters, tep_plugin_print_options \- Print libtraceevent internal information\&.
.SH "SYNOPSIS"
.sp
.nf
\fB#include <event\-parse\&.h>\fR
\fB#include <trace\-seq\&.h>\fR

void \fBtep_print_printk\fR(struct tep_handle *tep);
void \fBtep_print_funcs\fR(struct tep_handle *tep);

.SH "DESCRIPTION"
.sp
The \fItep_print_printk()\fR function prints the printk string formats that were stored for this tracing session\&. The \fItep\fR argument is trace event parser context\&.
.sp
The \fItep_print_funcs()\fR function prints the stored function name to address mapping for this tracing session\&. The \fItep\fR argument is trace event parser context\&.
.sp
The \fItep_set_test_filters()\fR function sets a flag to test a filter string\&. If this flag is set, when \fItep_filter_add_filter_str()\fR API as called, it will print the filter string instead of adding it\&. The \fItep\fR argument is trace event parser context\&. The \fItest_filters\fR argument is the test flag that will be set\&.
.sp
The \fItep_plugin_print_options()\fR function writes a list of the registered plugin options into \fIs\fR\&.
