Compatibility: DPMI 1.0+

Expects: AX    0505H

ESI   memory block handle (as obtained via INT 31H 0504H)

ECX   new size of block, in bytes (must not be 0)

EDX   flags:  bit 0: 1=create committed pages

0=create uncommitted pages

bit 1: 1=descriptors require update (see Notes)

0=do not update descriptors

2-31: (reserved; should be 0)

Returns: CF    NC (clear) if successful; else AX = DPMI Error Code

EBX   new linear base address of allocated block

ESI   new handle used to resize and free this block

Info: Changes the size of a linear memory block allocated via

INT 31H 0504H.

Notes: If bit 1 of EDX is set, then you must identify the descriptors

which need to be updated as follows:  ES:EBX is the address of a

series of 2-byte selectors whose descriptors need updating and

EDI is the size of the array, in words.
