ZOOM offers an interface to a subset of the Z39.50 extended services as well as a few privately defined ones:
Z39.50 Item Order (ILL). See Section 7.1, “Item Order”.
Record Update. This allows a client to insert, modify or delete records. See Section 7.2, “Record Update”.
Database Create. This a non-standard feature. Allows a client to create a database. See Section 7.3, “Database Create”.
Database Drop. This a non-standard feature. Allows a client to delete/drop a database. See Section 7.4, “Database Drop”.
Commit operation. This a non-standard feature. Allows a client to commit operations. See Section 7.5, “Commit Operation”.
To create an extended service operation a ZOOM_package
must be created. The operation is a five step operation. The
package is created, package is configured by means of options,
the package is send, result is inspected (by means of options),
the package is destroyed.
ZOOM_package ZOOM_connection_package(ZOOM_connection c,
ZOOM_options options);
const char *ZOOM_package_option_get(ZOOM_package p,
const char *key);
void ZOOM_package_option_set(ZOOM_package p, const char *key,
const char *val);
void ZOOM_package_send(ZOOM_package p, const char *type);
void ZOOM_package_destroy(ZOOM_package p);
The ZOOM_connection_package creates a
package for the connection given using the options specified.
Functions ZOOM_package_option_get and
ZOOM_package_option_set gets and sets
options.
ZOOM_package_send sends
the package the via connection specified in
ZOOM_connection_package.
The type specifies the actual extended service
package type to be sent.
