How about:
"TRACEPOINT_EVENT()" and "#define TRACEPOINT_CREATE" ?
Ideally, I'd like to settle this API and release a UST 0.13 this week,
so people who want to start instrumenting their code can use the new
Markers API while we move to the TRACEPOINT_EVENT infrastructure.
Tracepoint event sounds good... you sort of connect tracepoints with
events then.... :-)
TRACEPOINT_CREATE would be what exactly? Afraid I got a bit lost...

UST Markers (main API members):
#include<ust/marker.h>
ust_marker(name, "fmt", ...)
UST_MARKER_NOARGS
GET_UST_MARKER()
DEFINE_UST_MARKER(name, ...)
ust_marker_probe_unregister()
ust_marker_probe_register()
ust_marker_synchronize_unregister()
UST_MARKER_LIB
Will be eventually phased-out with the new TRACEPOINT_TEMPLATE()
and
CTF:
DEFINE_UST_MARKER_TP()
ust_marker_tp()
No problem. Simpler is better and this API will be UST specific so
rtfm at that point :).
Just one question, these are UST internal right? I mean, not to be
confused with the ustctl functions?
Not sure I understand your question. But the "ust_marker()" is an API
exposed to application willing to do ad-hoc tracing relying
directly on
UST. These application libraries using ust_marker() would have to
define
UST_MARKER_LIB. UST_MARKER_NOARGS is also needed. For the rest, I
agree
that it's more UST-internal.
