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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

VMMcall _GetNulPageHandle
 
mov     [NulPage], eax          ; handle of system nul page
 
The _GetNulPageHandle service returns the memory handle of the system nul
page. This page is used to occupy regions of the address space which are
unused but for which it is not desirable to cause a page fault when
accessed. The system nul page can be mapped to multiple locations in the
system, so its contents are always random.
 
This service has no parameters.
 
Return Value
 
The EAX register contains the memory handle of the system nul page.
