IDebugDataSpaces3::WriteVirtualUncached method (dbgeng.h)
The WriteVirtualUncached method writes data to the target's virtual address space.
Syntax
HRESULT WriteVirtualUncached(
[in] ULONG64 Offset,
[in] PVOID Buffer,
[in] ULONG BufferSize,
[out, optional] PULONG BytesWritten
);
Parameters
[in] Offset
Specifies the location in the target's virtual address space to be written.
[in] Buffer
Specifies the buffer to write the memory from.
[in] BufferSize
Specifies the size in bytes of the buffer. This is also the number of bytes requested to be written.
[out, optional] BytesWritten
Receives the number of bytes that were actually written. If it is set to NULL, this information is not returned.
Return value
This method can also return error values. See Return Values for more details.
| Return code | Description |
|---|---|
|
The method was at least partially successful. BytesWritten indicates the number of bytes successfully written, which may be less than BufferSize. |
Remarks
This method writes the buffer to the memory in the target's virtual address space.
This method behaves identically to WriteVirtual, except that it avoids using the virtual memory cache. It is therefore useful for reading inherently volatile virtual memory, such as memory-mapped device areas, without contaminating or invalidating the cache.
