[RFC][PATCH v2 04/24] tools/lib/traceevent, tools/perf: Rename pevent alloc / free APIs

From: Steven Rostedt
Date: Wed Aug 08 2018 - 14:09:23 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_alloc, pevent_free, pevent_event_info and pevent_func_resolver_t
