Module Name:

    uasp.h

Abstract:

    Private declartions for function defined in uasp.c, aliasp.c,
    groupp.c, and userp.c

Author:

    Cliff Van Dyke (cliffv) 20-Feb-1991

Environment:

    User mode only.
    Contains NT-specific code.
    Requires ANSI C extensions: slash-slash comments, long external names.

Revision History:

    17-Apr-1991 (cliffv)
        Incorporated review comments.
    09-Apr-1992 JohnRo
        Prepare for WCHAR.H (_wcsicmp vs _wcscmpi, etc).
    28-Oct-1992 RitaW
    Added private support routines for localgroups (aliases)
    30-Nov-1992 Johnl
    Added AliaspOpenAlias2 (same as AliaspOpenAlias except operates on
    RID instead of account name).
