What did you try so far? Documentation is available, so what's the problem?

If you try to map at something other than a multiple of the allocation granularity, the mapping will fail and GetLastError will return ERROR_MAPPED_ALIGNMENT

From MSDN
To obtain the memory allocation granularity of the system, use the GetSystemInfo function, which fills in the members of a SYSTEM_INFO structure.

For files that are larger than the address space, you can only map a small portion of the file data at one time. When the first view is complete, you can unmap it and map a new view.

To obtain the size of a view, use the VirtualQuery function.
