[RFC][PATCH v2 08/24] tools/lib/traceevent, tools/perf: Rename pevent_read_number_* APIs
From: Steven Rostedt
Date: Wed Aug 08 2018 - 14:09:03 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_read_number, pevent_read_number_field
