Copyright (c) 1991 Microsoft Corporation
Module Name:
userp.c
Abstract:
Internal routines for supporting the NetUser API functions
Author:
Cliff Van Dyke (cliffv) 26-Mar-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.
17-Jan-1992 (madana)
Added a new entry in the UserpUasSamTable to support account
rename.
20-Jan-1992 (madana)
Sundry API changes.

Routine Description:
Get the information on one user and fill that information into an

Arguments:
DomainHandle - Domain Handle for the Account domain.
DomainId - Domain Id corresponding to DomainHandle
BuiltinDomainHandle - Domain Handle for the builtin domain. Need only be
specified for info level 1, 2, 3, and 11.
UserName - User name of the user to query.
UserRelativeId - Relative ID of the user to query.
Level - Level of information required. level 0, 1, 2, 3, 10, 11 and 20
are valid.
PrefMaxLen - Callers prefered maximum length
BufferDescriptor - Points to a structure which describes the allocated
buffer. On the first call, pass in BufferDescriptor->Buffer set
to NULL. On subsequent calls (in the 'enum' case), pass in the
structure just as it was passed back on a previous call.
The caller must deallocate the BufferDescriptor->Buffer using
MIDL_user_free if it is non-null.
IsGet - True iff this is a 'get' call and not an 'enum' call.
Return Value:
Error code for the operation.
If this is an Enum call, the status can be ERROR_MORE_DATA implying that
the Buffer has grown to PrefMaxLen and that this much data should
be returned to the caller.

Routine Description:
Set the parameters on a user account in the user accounts database.
Arguments:
DomainHandle - Domain Handle for the domain.
PSID DomainId - Domain Sid for DomainHandle
UserHandle - User Handle of the already open group. If one is not
specified, one will be openned then closed. If one is specified,
it must be open with adequate access.
BuiltinDomainHandle - Domain Handle for the builtin domain. Need only be
specified for info level 1, 2, 3, 22, 1005 and 1010. Need not
be specified when a user is created.
UserRelativeId - Relative Id of the user.
UserName - Name of the user to set.
Level - Level of information provided.
Buffer - A pointer to the buffer containing the user information
structure.
ParmError - Optional pointer to a DWORD to return the index of the
first parameter in error when ERROR_INVALID_PARAMETER is returned.
If NULL, the parameter is not returned on error.
Return Value:
Error code for the operation.
NOTE: LogonServer field that is passed in UAS set structure is never
used or validated. It is simply ignored.

Return Value:
