57: /* Reply Codes for MMDF
58: *
59: * Based on: "Revised FTP Reply Codes", by Jon Postel & Nancy Neigus Arpanet
60: * RFC 640 / NIC 30843, in the "Arpanet Protocol Handbook", E. Feinler
61: * and J. Postel (eds.), NIC 7104, Network Information Center, SRI
62: * International: Menlo Park, CA. (NTIS AD-A0038901)
63: *
64: * Actual values are different, but scheme is same. Codes must fit into
65: * 8-bits (to pass on exit() calls); fields are packed 2-3-3 and interpreted
66: * as octal numbers.
67: *
68: * Basic format:
69: *
70: * 0yz: positive completion; entire action done
71: * 1yz: positive intermediate; only part done
72: * 2yz: Transient negative completion; may work later
73: * 3yz: Permanent negative completion; you lose forever
74: *
75: * x0z: syntax
76: * x1z: general; doesn't fit any other category
77: * x2z: connections; truly transfer-related
78: * x3z: user/authentication/account
79: * x4x: mail
80: * x5z: file system
81: *
82: * 3-bit z field is unique to the reply. In the following,
83: * the RP_xVAL defines are available for masking to obtain a field.
