67 /* Reply Codes for MMDF
69 * Based on: "Revised FTP Reply Codes", by Jon Postel & Nancy Neigus Arpanet
70 * RFC 640 / NIC 30843, in the "Arpanet Protocol Handbook", E. Feinler
71 * and J. Postel (eds.), NIC 7104, Network Information Center, SRI
72 * International: Menlo Park, CA. (NTIS AD-A0038901)
74 * Actual values are different, but scheme is same. Codes must fit into
75 * 8-bits (to pass on exit() calls); fields are packed 2-3-3 and interpreted
80 * 0yz: positive completion; entire action done
81 * 1yz: positive intermediate; only part done
82 * 2yz: Transient negative completion; may work later
83 * 3yz: Permanent negative completion; you lose forever
86 * x1z: general; doesn't fit any other category
87 * x2z: connections; truly transfer-related
88 * x3z: user/authentication/account
92 * 3-bit z field is unique to the reply. In the following,
93 * the RP_xVAL defines are available for masking to obtain a field.
