Environment:
|
||
|
|
|
||
|
|
Interface is portable to any flat, 32-bit environment. (Uses Win32
|
||
|
|
typedefs.) Requires ANSI C extensions: slash-slash comments, long
|
||
|
|
external names. Code itself only runs under NT.

Routine Description:
|
||
|
|
|
||
|
|
This routine obtains the domain id from LSA for the local domain.
|
||
|
|
The routine is a superset of NetpGetDomainId().
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
TypeWanted - Indicates which type of local domain ID is wanted:
|
||
|
|
the primary one or the accounts one.
|
||
|
|
|
||
|
|
RetDomainId - This is a pointer to the location where the pointer
|
||
|
|
to the domain id is to be placed. This must be freed via LocalFree().
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
NERR_Success - If the operation was successful.
|
||
|
|
|
||
|
|
It will return assorted Net or Win32 error messages if not.
