Typedef Documentation

A configuration object passed to some extension interfaces.

This is an opaque type: configuration values can be queried using WT_EXTENSION_API::config_get.

A handle for a scan through a configuration string.

This is an opaque type returned by WT_EXTENSION_API::config_scan_begin. Configuration values can be queried using WT_EXTENSION_API::config_scan_next. Call WT_EXTENSION_API::config_scan_end when finished to release resources.

int wiredtiger_extension_init	(	WT_CONNECTION *	connection,
		WT_CONFIG_ARG *	config
	)

Entry point to an extension, called when the extension is loaded.

Parameters

connection	the connection handle
config	the config information passed to WT_CONNECTION::load_extension

Returns: zero on success and a non-zero error code on failure. See Error Returns for details.

int wiredtiger_extension_terminate ( WT_CONNECTION * connection )

Optional cleanup function for an extension, called during WT_CONNECTION::close.

Parameters

connection the connection handle

Returns: zero on success and a non-zero error code on failure. See Error Returns for details.
