[RFC][PATCH v2 24/24] tools/lib/traceevent: Rename static variables and functions in event-parse.c

From: Steven Rostedt
Date: Wed Aug 08 2018 - 14:07:08 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
static variables and functions in event-parse.c: pevent_func_params,
__pevent_parse_format, __pevent_parse_event, pevent_error_str, pevent_search_event
