I''m not sure what you are looking for but probably you should use PID
provider. Something like:

pidXXXX::your_function:entry
{
  self->t = timestamp;
  self->vt = vtimestamp;
}

pidXXXX::you_function:return
/self->t/
{
  @times[probefunc, "time"] = sum(timestamp - self->t);
  @times[probefunc, "vtime"] = sum(vtimestamp - slef->vt);

  self->t = 0;
  self->vt = 0;
}


This will give you execution times of your function (and all functions
that are called within this function as well - simple modification and
you''ll get times only for that function excluding all calls to other).
