IDebugDataSpaces4::ReadVirtualUncached method (dbgeng.h)
The ReadVirtualUncached method reads memory from the target's virtual address space.
Syntax
HRESULT ReadVirtualUncached(
[in] ULONG64 Offset,
[out] PVOID Buffer,
[in] ULONG BufferSize,
[out, optional] PULONG BytesRead
);
Parameters
[in] Offset
Specifies the location in the target's virtual address space to be read.
[out] Buffer
Specifies the buffer to read the memory into.
[in] BufferSize
Specifies the size in bytes of the buffer. This is also the number of bytes being requested.
[out, optional] BytesRead
Receives the number of bytes that were read. If it is set to NULL, this information is not returned.
Return value
| Return code | Description |
|---|---|
|
The method was successful. It is possible that BytesRead is less than BufferSize, but at least one byte of data is being returned. |
This method can also return error values. See Return Values for more details.
Remarks
This method fills the buffer with the contents of the memory in the target's virtual address space.
This method behaves identically to ReadVirtual, 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.
