INT 31H 000eH: Query Multiple Descriptors

                                                    Compatibility: DPMI 0.9+ 
 Expects: AX    000eH
          CX    number of descriptors to copy
          ES:DI (or ES:EDI) sel:off of buffer describing which selectors you
                want and space to receive data
 Returns: CF    NC (clear) if successful;
                else AX = DPMI Error Code
                     CX = number of entries copied
          ES:DI (or ES:EDI) buffer contains selectors and LDT entries
    Info: This copies a series of LDT entries into a local buffer.  You
          must pre-fill the buffer with the desired selectors, with 8-byte
          gaps between each:

          The buffer is be formatted as:

            Offset Size Contents
            ▀▀▀▀▀▀ ▀▀▀▀ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
             +0      2  wSel1       set by caller
             +2      8  rDesc1      filled by host
            +0aH     2  wSel2       set by caller
            +0cH     8  rDesc2      filled by host

    Note: If the call fails due to an invalid selector, the host will
          return CX as the number of valid selectors that it found before
          encountering the bad apple.
