## 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.
