Specifying the Base Address of a Memory-Mapped File

Just as you can use the VirtualAlloc function to suggest an initial address to reserve address space, you can also use the MapViewOfFileEx function instead of the MapViewOfFile function to suggest that a file be mapped into a particular address:

PVOID MapViewOfFileEx(
   HANDLE hFileMappingObject,
   DWORD dwDesiredAccess,
   DWORD dwFileOffsetHigh,
   DWORD dwFileOffsetLow,
   SIZE_T dwNumberOfBytesToMap,
   PVOID pvBaseAddress);

All the parameters and the return value for this function are identical to those of the MapViewOfFile function with the single exception of the last parameter, pvBaseAddress. In this parameter, you specify a target address for the file you’re mapping. As with VirtualAlloc, the target address ...
