Function silc_ske_set_callbacks
SYNOPSIS

        void silc_ske_set_callbacks(SilcSKE ske,
                                    SilcSKESendPacketCb send_packet,
                                    SilcSKECb payload_receive,
                                    SilcSKEVerifyCb verify_key,
                                    SilcSKECb proto_continue,
                                    SilcSKECheckVersion check_version,
                                    void *context);

DESCRIPTION

        Sets the callback functions for the SKE session.

        The `send_packet' callback is a function that sends the packet to
        network. The SKE library will call it at any time packet needs to
        be sent to the remote host.

        The `payload_receive' callback is called when the remote host's Key
        Exchange Start Payload has been processed.  The payload is saved
        to ske->start_payload if the application would need it.  The application
        must also provide the payload to the next state of the SKE.

        The `verify_key' callback is called to verify the received public key
        or certificate.  The verification process is most likely asynchronous.
        That is why the application must call the completion callback when the
        verification process has been completed. The library then calls the user
        callback (`proto_continue'), if it is provided to indicate that the SKE
        protocol may continue. If this SKE session context is used to perform
        rekey, this callback usually is not provided as argument since sending
        public key in rekey is not mandatory. Setting this callback implies
        that remote end MUST send its public key, and this could cause
        problems when performing rekey. When doing normal SKE session this
        callback should be set.

        The `proto_continue' callback is called to indicate that it is
        safe to continue the execution of the SKE protocol after executing
        an asynchronous operation, such as calling the `verify_key' callback
        function, which is asynchronous. The application should check the
        ske->status in this function to check whether it is Ok to continue
        the execution of the protocol.

        The `check_version' callback is called to verify the remote host's
        version. The application may check its own version against the remote
        host's version and determine whether supporting the remote host
        is possible.

        The `context' is passed as argument to all of the above callback
        functions.
