- modification history
- --------------------
- 01i,26aug97,spm removed compiler warnings (SPR #7866)
- 01h,08sep94,jmm replaced all routines with routines from rpcgen
- 01g,15sep92,jcf changed "struct name" to "struct nfsName".
- 01f,26may92,rrr the tree shuffle
- 01e,19nov91,rrr shut up some ansi warnings.
- 01d,04oct91,rrr passed through the ansification filter
- -changed functions to ansi style
- -changed includes to have absolute path from h/
- -changed copyright notice
- 01c,15may90,dnw fixed bug in xdr_{pathstat,attrstat,diropres,readreply,
- readdirres} of returning FALSE if returned NFS status
- was not NFS_OK, and xdr_{mountentries,exportbody} returning
- FALSE if more_entries was FALSE. 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.

- DESCRIPTION
- This module contains the eXternal Data Representation (XDR) routines for NFS.
- This module could (and should) be generated from a .x, but there have
- been tweaks as noted in the mod history above.
- As of 8 Sep 1994, the routines in this file are exactly as generated from
- rpcgen. All of the old modified routines have been removed.
