Subject: [PATCH 06/24] tools lib traceevent, perf tools: Rename pevent parse APIs
Date: Tue, 21 Aug 2018 16:33:10 +0300	[thread overview]
Message-ID: <20180821133328.3249-7-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20180821133328.3249-1-tz.stoyanov@gmail.com>

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
