IDebugDataSpaces4::ReadControl method (dbgeng.h)

The ReadControl method reads implementation-specific system data.

Syntax

HRESULT ReadControl(
  [in]            ULONG   Processor,
  [in]            ULONG64 Offset,
  [out]           PVOID   Buffer,
  [in]            ULONG   BufferSize,
  [out, optional] PULONG  BytesRead
);

Parameters

[in] Processor

Specifies the processor whose information is to be read.

[in] Offset

Specifies the offset in the control space of the memory to read.

[out] Buffer

Receives the data read from the control-space memory.

[in] BufferSize

Specifies the size in bytes of the buffer Buffer. This is the maximum number of bytes that will be read.

[out, optional] BytesRead

Receives the number of bytes returned in the buffer Buffer. If BytesRead is NULL, this information is not returned.

Return value

This method can also return error values. See Return Values for more details.
