Get Selector Increment Value [0.9]

The DPMI functions Allocate LDT Descriptors (Int 31H Function 0000H) and Allocate DOS Memory Block (Int 31H Function 0100H) can allocate an array of contiguous descriptors, but only return a selector for the first descriptor. The value returned by this function can be used to calculate the selectors for subsequent descriptors in the array.

Call With

AX = 0003H
