71 /* Reply Codes for MMDF
73 * Based on: "Revised FTP Reply Codes", by Jon Postel & Nancy Neigus Arpanet
74 * RFC 640 / NIC 30843, in the "Arpanet Protocol Handbook", E. Feinler
75 * and J. Postel (eds.), NIC 7104, Network Information Center, SRI
76 * International: Menlo Park, CA. (NTIS AD-A0038901)
78 * Actual values are different, but scheme is same. Codes must fit into
79 * 8-bits (to pass on exit() calls); fields are packed 2-3-3 and interpreted
84 * 0yz: positive completion; entire action done
85 * 1yz: positive intermediate; only part done
86 * 2yz: Transient negative completion; may work later
87 * 3yz: Permanent negative completion; you lose forever
90 * x1z: general; doesn't fit any other category
91 * x2z: connections; truly transfer-related
92 * x3z: user/authentication/account
96 * 3-bit z field is unique to the reply. In the following,
97 * the RP_xVAL defines are available for masking to obtain a field.
