BUG: Protected-Mode GlobalCompact() Return Not Free Memory (76686)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
This article was previously published under Q76686 SYMPTOMS
When Windows is running in one of its protected modes, the value returned
by the GlobalCompact() API does not accurately reflect the amount of free
memory available in the system.
In enhanced mode, Windows can swap memory objects to disk. This process
takes a long time relative to accessing an object in memory. Therefore,
GlobalCompact() returns the amount of memory available without performing
any paging.
In standard mode, GlobalCompact() never reports more than 1 megabyte (MB)
of memory free because of a memory allocation limit on the 80286 chip.
STATUS
Microsoft has confirmed that this problem occurs in Windows versions 3.0
and 3.1. We are researching this problem and will post new information here
as it becomes available.
