  * DESCRIPTION
  *
  *    Same as silc_command_payload_encode_va except that this is used to 
- *    encode strictly command reply packets. The command status message
- *    to be returned is sent as extra argument to this function. The `argc'
- *    must not count `status' as on argument.
+ *    encode strictly command reply packets.  The `argc' must not count 
+ *    `status' and `error' as arguments.  The `status' includes the
+ *    command reply status.  If single reply will be sent then it includes
+ *    SILC_STATUS_OK if error did not occur.  It includes an error value
+ *    if error did occur.  In this case `error' field is ignored.  If
+ *    there will be multiple successful command replies then the `status'
+ *    includes a list value and `error' is ignored.  If there will
+ *    multiple error replies the `status' includes a list value, and
+ *    the `error' includes an error value.  Thus, the `error' value is
+ *    specified only if there will be list of errors.
+ *
+ * NOTES
+ *
+ *    Protocol defines that it is possible to send both list of successful
+ *    and list of error replies at the same time, as long as the error
+ *    replies are sent after the successful replies.

+ *    error occurred.  In this case the `error' will include the actual
+ *    error status.  The `status' can be in this case some list value
+ *    which indicates that there will be list of errors.
