X-Hacker.org- Ralf Brown's Interrupt List (Part 1,2) - int 15 - desqview 2.2+ - assertmap - get/set mapping context http://www.X-Hacker.org [<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
INT 15 - DESQview 2.2+ - "ASSERTMAP" - GET/SET MAPPING CONTEXT
        AX = 1117h
        BX = 0000h      get current mapping context without setting
             nonzero    set new mapping context
Return: BX = mapping context in effect before call
        interrupts enabled
Notes:  this function differs from AX = DE17h for DESQview v2.20 through 2.25
        mapping contexts determine conventional-memory addressability; setting
          a mapping context ensures that the associated program and data areas
          are in memory for access.  Usable by drivers, TSRs and shared
          programs.
        caller need not be running under DESQview, but must ensure that the
          stack in use will not be mapped out by the call
