[lttng-dev] Question about TRACEPOINT_EVENT_CLASS and TRACEPOINT_EVENT_INSTANCE

[Eugene Ivanov]

Hi,

I found description of TRACEPOINT_EVENT_CLASS on the website and
in ust-tracepoint-event.h as well, but it is not documented in the
lttng-ust man page. According the header TRACEPOINT_EVENT_INSTANCE declares
an instance of a tracepoint, with its own provider and name. Does it mean
that I can define classes for usage in different providers? Why do we need
provider in _CLASS then? According the code on the first glance it seems
that it is required that CLASS and INSTANCE must share in same provider.
