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.
