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_.
