This had the effect of		   invalidating the entire RPC reply (hence RPC_CANTDECODERES).		   This was due to a mistake in the original xdr_nfs.x file		   that had no "default" case specifed for these unions		   (should be "default: void;").		 changed to use POSIX NAME_MAX from dirent.h:		   - xdr_filename to take NAME_MAX instead of NFS_MAXNAMLEN		   - xdr_path to take PATH_MAX instead of NFS_MAXPATHLEN		 recoded xdr_mountlist and xdr_mountentries to not be recursive.		   This is patterned after the discussion in the "Advanced		   Topics" chapter of the "XDR: Sun Technical Notes" document		   (xdr.nts.ms distributed with rpc 4.0), except that I		   believe the example in the document is wrong.  The example		   references memory that may have been freed, even though		   the narrative says they are avoiding exactly that.		   Note that xdr_readdirres and xdr_exportbody remain		   recursive, although they could be coded in the same way		   as xdr_mountentries.		 added xdr_readdirresOne which reads only one entry from		   a directory read request, and discards the rest.		   This is used by nfsDirReadOne() in nfsLib and is strictly		   a hack to avoid unnecessary malloc/frees for the unwanted		   additional entries.01b,20oct89,hjb  changed "struct timeval" to nfsTimeval to avoid conflicts		 with the definition of "struct timeval" in "utime.h".01a,19apr88,llk  created.*//*DESCRIPTIONThis module contains the eXternal Data Representation (XDR) routines for NFS.This module could (and should) be generated from a .x, but there havebeen tweaks as noted in the mod history above.As of 8 Sep 1994, the routines in this file are exactly as generated fromrpcgen.
