int hw_error(hw_link); resource hw_link: Connection ID to Hyperwave server

Returns

Error code from the previous command; FALSE if an error occurs

Description

hw_error() fetches the error code generated by the previously executed Hyperwave command. An error code of 0means that the previous operation was successful. For a textual explanation of the possible error codes, see hw_errormsg() .

hw_gettext($hw_link, $document_id);
if (hw_error()) {
