[RFC][PATCH 06/24] tools/lib/traceevent, tools/perf: Rename pevent parse APIs

From: Steven Rostedt
Date: Wed Aug 08 2018 - 12:15:23 EST


From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@xxxxxxxxx>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_parse_event, pevent_parse_format, pevent_parse_header_page
