Subject[PATCH 10/66] libtraceevent: Man pages fix, changes in event printing APIs
Date
From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

APIs for printing various trace event information were redesigned to be
more simple. However, the main libtraceevent man page was not updated
with those changes. The documentation is updated to describe the new
event print API.
