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\&. .SH "EXAMPLE" .sp .if n \{\ .RS 4 .\} .nf #include #include \&.\&.\&. 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); \&.\&.\&. .fi .if n \{\ .RE .\} .SH "FILES" .sp .if n \{\ .RS 4 .\} .nf \fBevent\-parse\&.h\fR Header file to include in order to have access to the library APIs\&. \fB\-ltraceevent\fR Linker switch to add when building a program that uses the library\&. .fi .if n \{\ .RE .\} .SH "SEE ALSO" .sp \fIlibtraceevent(3)\fR, \fItrace\-cmd(1)\fR .SH "AUTHOR" .sp .if n \{\ .RS 4 .\} .nf \fBSteven Rostedt\fR <\m[blue]\fBrostedt@goodmis\&.org\fR\m[]\&\s-2\u[1]\d\s+2>, author of \fBlibtraceevent\fR\&. \fBTzvetomir Stoyanov\fR <\m[blue]\fBtz\&.stoyanov@gmail\&.com\fR\m[]\&\s-2\u[2]\d\s+2>, author of this man page\&. .fi .if n \{\ .RE .\} .SH "REPORTING BUGS" .sp Report bugs to <\m[blue]\fBlinux\-trace\-devel@vger\&.kernel\&.org\fR\m[]\&\s-2\u[3]\d\s+2> .SH "LICENSE" .sp libtraceevent is Free Software licensed under the GNU LGPL 2\&.1 .SH "RESOURCES" .sp \m[blue]\fBhttps://git\&.kernel\&.org/pub/scm/libs/libtrace/libtraceevent\&.git/\fR\m[] .SH "NOTES" .IP " 1." 4 rostedt@goodmis.org .RS 4 \%mailto:rostedt@goodmis.org .RE .IP " 2." 4 tz.stoyanov@gmail.com .RS 4 \%mailto:tz.stoyanov@gmail.com .RE .IP " 3." 4 linux-trace-devel@vger.kernel.org .RS 4 \%mailto:linux-trace-devel@vger.kernel.org .RE
