{
{   SEGMENT_ATTRIBUTES_P: (INPUT) This parameter is a pointer to an array
{          of segment_attributes to be assigned to the segment.
{
{   POINTER_KIND: (INPUT) This parameter specifies the type of pointer
{          to be constructed for the segment.
{
{   ACCESS_SELECTIONS: (INPUT) This parameter specifies  the mode of access
{          to the segment (sequential or random).
{
{   POINTER: (OUTPUT) This parameter specifies the process virtual address
