Int 31/AX=0505h

DPMI 1.0+ - RESIZE LINEAR MEMORY BLOCK

AX = 0505h
ESI = memory block handle
ECX = new size in bytes (nonzero)
EDX = flags
bit 0:
Create committed pages rather than uncommitted pages
bit 1:
Segment descriptor update required
ES:EBX -> buffer containing array of WORDs with selectors
EDI = number of selectors in array
bits 2-31 reserved (0)

Return:
CF clear if successful
EBX = new linear base address
ESI = new memory block handle
CF set on error
AX = error code (8001h,8012h-8014h,8016h,8021h,8023h)(see #03143)

Notes: Only supported by 32-bit DPMI hosts, but may be used by 16-bit clients. The old memory block handle becomes invalid. If EDX bit 1 set and the block's base address is changed, DPMI updates all descriptors for selectors in the update buffer which fall within the memory block
