Subject: [PATCH v2 07/10] tools lib traceevent: Rename input arguments of libtraceevent APIs from pevent to tep
Date: Mon, 8 Apr 2019 18:23:37 +0300 [thread overview]
Message-ID: <20190408152340.12450-8-tstoyanov@vmware.com> (raw)
In-Reply-To: <20190408152340.12450-1-tstoyanov@vmware.com>
Input arguments of libtraceevent APIs are renamed from "struct
tep_handle *pevent" to "struct tep_handle *tep". This makes the API
consistent with the chosen naming convention: tep (trace event parser),
instead of the old pevent.
