/* It defines values for missing or RPC2/Coda specific errnos */
 
/* RPC2 converts errno values to it's own platform independent numbering
 * - Errors returned by RPC's are platform independent.
 * - Accommodate Coda specific errors (like VSALVAGE) as well as system errors.
 * - Quick and easy translation of errors:
 *   a) from RPC2/Coda to system errors (typically for clients)
 *   b) from system to RPC2/Coda errors (typically for servers)
 *   c) provide a "perror" like function.
 * - Coda servers should only return errors which all of the client
 *   platforms can handle.
 * - If errors arrive on certain clients/servers and are not recognized
 *   a log message is printed and a default error code (4711) is returned.
