Module Name:
RemTypes.h
Abstract:
This header file defines character values used in descriptor strings in
Remote Admin Protocol.
NOTES - All pointer types are lower case, except for buffer pointers,
and the null pointer.
- REM_BYTE should not be used for parameters, since data is
never placed on the stack as individual bytes.
- REM_NULL_PTR is never specified in the call, but may be
used to replace a pointer type if the pointer itself is NULL.
- In some cases as indicated below, a descriptor character
can indicate an array of data items, if followed by an
ASCII representation of the number of items. For pointer
types, this is a count of the data items themselves, not
the pointers. For example, 'b12' describes a pointer
to 12 bytes of data, not 12 pointers to byte values.
Author:
LanMan 2.x people.
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
15-Mar-1991 Shanku Niyogi (w-shanku)
Ported to NT format, and added special 32-bit descriptor characters.
21-Aug-1991 Jim Waters (t-jamesw)
Added REM_ASCIZ_COMMENT.
16-Aug-1992 JohnRo
RAID 2920: Support UTC timezone in net code.
