MapViewOfFileNuma2 function (memoryapi.h)
Maps a view of a file or a pagefile-backed section into the address space of the specified process.
PVOID MapViewOfFileNuma2(
[in] HANDLE FileMappingHandle,
[in] HANDLE ProcessHandle,
[in] ULONG64 Offset,
[in, optional] PVOID BaseAddress,
[in] SIZE_T ViewSize,
[in] ULONG AllocationType,
[in] ULONG PageProtection,
[in] ULONG PreferredNode
);
[in] FileMappingHandle
A HANDLE to a section that is to be mapped into the address space of the specified process.
[in] ProcessHandle
A HANDLE to a process into which the section will be mapped.
[in] Offset
The offset from the beginning of the section. This must be 64k aligned.
[in, optional] BaseAddress
The desired base address of the view. The address is rounded down to the nearest 64k boundary. If this parameter is NULL, the system picks the base address.
[in] ViewSize
The number of bytes to map. A value of zero (0) specifies that the entire section is to be mapped.
[in] AllocationType
The type of allocation. This parameter can be zero (0) or one of the following constant values:
- MEM_RESERVE - Maps a reserved view
- MEM_LARGE_PAGES - Maps a large page view
[in] PageProtection
The desired page protection.
For file-mapping objects created with the SEC_IMAGE attribute, the PageProtection parameter has no effect, and should be set to any valid value such as PAGE_READONLY.
[in] PreferredNode
The preferred NUMA node for this memory.
Returns the base address of the mapped view, if successful. Otherwise, returns NULL and extended error status is available using GetLastError.
