jlinker-query

Arguments: &optional verify

Query the jLinker interface. Two values are returned. The first is t, nil, or :verified. The second returned value indicates the jlinker mode as follows:

• When the first returned value is non-nil, the second value is the keyword :socket or the keyword :native.
• When the first returned value is nil, the second value is the first element of *jlinker-init*.

If the interface is not running, the result is nil. If the interface is running and the verify argument is nil, return t. If the interface is running and the verify argument is non-nil, send a round-trip message to verify the connection (and return :verified if all is okay). If the interface appears to be malfunctioning, jlinker-end is called to shut down the connection completely.

See jlinker.htm for more information on the jLinker facility.
