WOWGetVDMPointerFix

The WOWGetVDMPointerFix function converts a 16:16 address to the equivalent linear address.

Windows 95 and Windows 98: This function calls the GlobalFix function before returning the linear address so that the 16-bit memory block will not be moved around in the 16-bit global heap.

Windows NT: This function behaves like the WOWGetVDMPointer function. The memory is not fixed.

LPVOID WINAPI WOWGetVDMPointerFix(
  DWORD vp,            // 16:16 address
  DWORD dwBytes,       // size of vp block
  BOOL fProtectedMode  // protected mode flag
);
 

Parameters

vp

Valid 16:16 address.

dwBytes

Size of the block pointed to by vp.

fProtectedMode

One of the following flags:

1	The upper 16 bits are treated as a selector in the local descriptor table (16-bit protected mode pointer).
0	The upper 16 bits are treated as a real-mode segment value (real-mode 16:16 pointer).

Return Values

Returns a 32-bit address if successful. If the selector is invalid, the return value is NULL.
