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