Get Multiple Descriptors

Copies one or more local descriptor table (LDT) entries into
a client buffer.

Call With:

   AX     = 000EH
   CX     = number of descriptors to copy
   ES:(E)DI= selector:offset of a buffer in the following
           format:

           Offset   Length   Contents
           00H      2        Selector #1 (set by client)
           02H      8        Descriptor #1 (returned by
           host)
           0AH      2        Selector #2 (set by client)
           0CH      8        Descriptor #2 (returned by
           host)
           .        .        .
           .        .        .
           .        .        .

Returns:

   if function successful
   Carry flag= clear

   and buffer contains copies of the descriptors for the
   specified selectors

   if function unsuccessful
   Carry flag= set
   AX     = error code
           8022H   invalid selector
   CX     = number of descriptors successfully copied

Notes:

o  If an error occurs because of an invalid selector or
   descriptor, the function returns the number of
   descriptors which were successfully copied in CX.  All of
   the descriptors which were copied prior to the one that
   failed are valid.
o  32-bit programs must use ES:EDI to point to the buffer.
   16-bit programs should use ES:DI.
o  Refer to the rules for descriptor usage in Appendix D.
