sybase_set_message_handler

hi, During the Spanish translation of this function (sybase_set_message_handler), I had found that there is not mention Of the optional parameter included in the description, see: Description bool sybase_set_message_handler ( callback handler [, resource connection]) And I was wondering whether it behavior is like the “resource link_identifier” that is optional in the Sybase_query function, or what?, and if so a note should be raised in the function Sybase_set_message_handler, is that correct? Or should somebody test the functionality before any documentation change? I would like to hang the translation of this function, upon recommendation. Regards Enrique
