{
{   The purpose of this request is to create a transient segment that uses the
{ ACTIVE file of an existing segment as a PASSIVE file.
{
{    MMP$CREATE_SHADOW_SEGMENT (shadow_pva, shadow_offset, shadow_length,
{           pointer_kind, pva, status);
{
{ SHADOW_PVA :(input) This parameter specifies the segment pointer of the
{      segment to be shadowed.
{
{ SHADOW_OFFSET: (input) This parameter specifies the byte offset within the
{      segment from which to start shadowing.
{
{ SHADOW_LENGTH: (input) This parameter specifies the length of portion in
{      segment to be shadowed.
{
{ POINTER_KIND: (input) This parameter specifies the type of pointer to be
{      constructed for the segment.
{
{ PVA: (output) This parameter returns the process virtual address of the
{      transient segment.
{
{ STATUS: (output) This parameter specifies the request status returned.
