From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>
Add the following functions to the libtracecmd library:
tracecmd_set_private() - set private data to tracecmd_input handle
tracecmd_get_private() - get private data from tracecmd_input handle
tracecmd_iterate_events() - iterate all events for a single buffer in a
trace.dat file (can filter on CPUs)
tracecmd_iterate_events_multi() - iterate all events from multiple buffers
in a trace.dat file. (Does not filter on CPUs).
tracecmd_filter_add() - Add a filter to a tracecmd_input handle that will
filter the iterator funtions.
tracecmd_filter_match() - Will test a record against a given filter to see
if it matches or not.
As change trace-cmd to use these functions instead of doing the same thing
internally.
Steven Rostedt (Google) (9):
tracecmd: Use make variable instead of if statement for zlib test
tracecmd library: Add tracecmd_iterate_events()
tracecmd utest: Add test to test using the libraries to read
tracecmd library: Add tracecmd_iterate_events_multi()
trace-cmd library: Allow callers to save private data in
tracecmd_input handlers
trace-cmd report: Use tracecmd_iterate_events_multi()
trace-cmd library: Add filtering logic for iterating events
trace-cmd report: Make filter arguments match their files
trace-cmd report: Use library tracecmd_filter_*() logic
