+ * This routine creates a general purpose error reply message.  It

+ * The error reply is built in "p", using the error code "e" and
+ * error text "e_string" given.  The length of the error reply is
+ * returned.
+ *
+ * The error reply is in the following format:
+ *
+ * unsigned char	KRB_PROT_VERSION	protocol version no.
+ * unsigned char	AUTH_MSG_APPL_ERR	message type
+ * (least significant
+ * bit of above)	HOST_BYTE_ORDER		local byte order
+ * 4 bytes		e			given error code
+ * string		e_string		given error text
