include dosmgr.inc VxDcall DOSMGR_BackFill_Allowed |
The DOSMGR_BackFill_Allowed service specifies whether the MS-DOS configuration allows for low-memory backfills.
The V86MMGR device calls this service.
This service has no parameters.
The carry flag is clear if backfilling is allowed. Otherwise, the carry flag is set.
This service depends on the high MS-DOS state. Certain high MS-DOS configurations prevent low memory 640K backfill from being possible.
