finding AUTO_INCREMENT type from client side

[Jim O'Quinn]

Is there any way to programmatically figure out
if a field is AUTO_INCREMENT?  I can do something 
like:

  for ($x=0; $x < $sth->numfields; $x++) {
    $colname  = $sth->name->[$x];
    $size     = $sth->length->[$x];
    $maxlen   = $sth->length->[$x];
    $type     = $sth->type->[$x];
  }

But from what I can tell, 'type' is a INT and
there is no way to tell if it is AUTO_INCREMENT
or not?

Does anyone know of a way to figure out if a
field is AUTO_INCREMENT?
