/**	GetUserDomain

The GetUserDomain function retrieves the name of the NT domain the user	is
logged in.

Parameters
	@param lpBuffer
		[out] Pointer to a buffer that receives a null-terminated string
		containing the domain name.
	@param nBufferSize
		[in] Specifies the size, in TCHARs, of the buffer pointed to
		by the lpBuffer parameter.


Return Values
	@return
	If the function succeeds, the return value is the number of TCHARs stored
	into the buffer pointed to by lpBuffer, not including the terminating
	null character.

	If the domain name can't be retrieved, the return value is zero.

	If the buffer pointed to by lpBuffer is not large enough, the return value
	is the buffer size, in TCHARs, required to hold the value string and its
	terminating null character.

Remarks
	Windows 95/98/Me: If the user is not logged in onto a NT domain server
	the name of the workgroup is returned.

Requirements
  Windows NT/2000/XP: Included in Windows NT 4 and later.
  Windows 95/98/Me: Included in Windows 95 and later.
  Header: Declared in Uwinapi.h; include Uwinapi.h.
  Library: Use Uwinapi.lib.
  Unicode: Implemented as Unicode and ANSI versions on Windows 95/98/Me/NT/2000/XP.
