Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

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.
 
Return Value
 
The carry flag is clear if backfilling is allowed. Otherwise, the carry flag
is set.
 
Comments
 
This service depends on the high MS-DOS state. Certain high MS-DOS
configurations prevent low memory 640k backfill from being possible.
