[lttng-dev] lttng-ust callback on trace start

[Benjamin Thaut]

Hi,

I searched the documentation and the source code for a while but didn't find anything,
is there any way to get a callback using the lttng-ust library when tracing starts? E.g. I don't want to poll if a certain tracepoint is enabled. I want to get notified when any tracing starts. A notification when a specific tracepoint is enabled would also be sufficient.
