yaz_ccl_conf

Description

This function configures the CCL query parser for a target with definitions of access points (CCL qualifiers) and their mapping to RPN. To map a specific CCL query to RPN afterwards call the yaz_ccl_parse() function. Each index of the array config is the name of a CCL field and the corresponding value holds a string that specifies a mapping to RPN. The mapping is a sequence of attribute-type, attribute-value pairs. Attribute-type and attribute-value is separated by an equal sign (=). Each pair is separated by white space.

Ejemplo 1. CCL configuration In the example below, the CCL parser is configured to support three CCL fields: ti, au and isbn. Each field is mapped to their BIB-1 equivalent. It is assumed that variable $id is the connection ID. $fields["ti"] = "1=4"; $fields["au"] = "1=1"; $fields["isbn"] = "1=7"; yaz_ccl_conf($id,$fields);
