IDebugDataSpaces4::WriteVirtual method (dbgeng.h)
The WriteVirtual method writes data to the target's virtual address space.
Syntax
HRESULT WriteVirtual(
[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 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 may only write to a cache of memory data when storing data. To avoid caching, use WriteVirtualUncached instead.
