ingres_errno - Get the last Ingres error number generated

SYNOPSIS
       int ingres_errno ([resource  $link])

DESCRIPTION
	Returns an integer containing the last error number. If no error was reported 0 is returned.

	If  a  $link  resource	is  passed  to	ingres_errno(3)  it  returns  the  last  error	recorded  for the link. If no link is passed, then
       ingres_errno(3) returns the last error reported using the default link.

	The function, ingres_errno(3), should always be called after executing a database query. Calling another function  before  ingres_errno(3)
       is called will reset or change any error code from the last Ingres function call.

PARAMETERS
	      o $link
		- The connection link identifier

RETURN VALUES
	Returns an integer containing the last error number. If no error was reported, 0 is returned.

	      $link = ingres_connect($database, $user, $password);

	      $error_code = ingres_errno($link);

	      if ( $error_code != 0 ) {
