The traceheader structure describes @@@. The structure includes the following members:
- next
- The size of the entire tracebuffer @@@size or actual?.
- flags
- Opaque variable; version information, event mask.
- reserved1
- Opaque variable; not yet used.
- num_events
- The number of events in the buffer.
- start
- Start of the trace.
- end
- End of the trace.
- begin_ptr
- @@@.
- end_ptr
- @@@.
- head_ptr
- @@@.
- tail_ptr
- @@@.
- max_events
- The maximum number of events that occur before the buffer flushes.
- spin
- Spin lock.
- base_addr
- The base address of the tracebuffer.
- reserved2
- Opaque variable; not yet used.
