[ltt-dev] Selection of trace file to read

[Mathieu Desnoyers]

Hi Francis,

Event filtering belongs at the lttv layer (which is higher up than the
ltttraceread library), after the state reconstruction machine has
received the events it asked for. LTTV does implement a hooking
mechanism for which you can register callbacks that are only called for
specific events.

Thanks,

Mathieu
