traceheader

Structure that describes header information

Synopsis:

#include <traceparser.h>

struct traceheader {
    struct tracebuf * next;
    uint32_t flags;
    uint32_t reserved1;
    uint32_t num_events;
    struct timeval start;
    struct timeval end;
    traceevent_t * begin_ptr;
    traceevent_t * end_ptr;
    traceevent_t volatile * head_ptr;
    traceevent_t volatile * tail_ptr;
    uint32_t max_events;
    struct intrspin spin;
    paddr_t baseaddr;
    uint32_t reserved2;
};

Library:

libtraceparser

Description:

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.

Classification:

QNX Neutrino
