2.04 - DPMI function 0003h Get Selector Increment Value

The DPMI function Allocate Descriptors (0000h) 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.


In: AX = 0003h
Out: CF clear
AX = selector increment value


a) The increment value is always a power of two.
