rpc-get

Arguments: (self rpc-port) (m rpc-message) &key (error-p t)

This method is used with the message handle returned by rpc-invoke to extract the result of the remote call. If the state of the message is :rms-done, one or more values are returned, one for each value returned by the remote call.

If the state of the message is :rms-throw, then the effect depends on the thrown result and the error-p argument. If error-p is nil, three values are always returned: the tag argument of the throw, the value of the throw, and an unwind-protect flag. When the unwind-protect flag is non-nil, the first two values are nil; the remote call was terminated by a throw past the return to this caller.

If error-p is non-nil, and the tag is non-nil, then the throw is continued in the calling environment. Otherwise an error is signaled.

If the state of the message is :rms-error an error is signaled, unless the error-p argument is nil. If the error-p argument is nil, the value returned is usually a list where the first element is a keyword denoting the error and the second element is a string describing the remote error in more detail.
