This function also calls hook_domainload(), which lets module developers overwrite or add to the $domain array.

Parameters

$domain_id: The domain_id taken from {domain}. Optional.

$subdomain: The string representation of a {domain} entry. Optional.

$reset: A boolean flag to clear the static variable if necessary.

Return value

An array containing the requested row from the {domain} table, plus the elements added by hook_domainload(). Returns -1 on failure.
