23: Revision History:
24:
25: DONNALI 08-29-91 Start recording history
26: donnali 09-11-91 change conversion macros
27: donnali 09-18-91 check in files for moving
28: STEVEZ 10-15-91 Merge with NT tree
29: donnali 10-28-91 add prototype
30: donnali 11-19-91 bugfix for strings
31: MIKEMON 12-17-91 DCE runtime API conversion
32: donnali 03-24-92 change rpc public header f
33: STEVEZ 04-04-92 add nsi include
34: mikemon 04-18-92 security support and misc
35: DovhH 04-24-24 Changed signature of <int>_from_ndr
36: (to unsigned <int>)
37: Added <base_type>_array_from_ndr routines
38: Comments:
39:
40: This file does not belong in runtime\mtrt. Needs to move to
41: ndrlib directory (after code freeze).
