ID3D11ShaderTrace::GetWrittenRegister method

Retrieves information about a register that was written by a step in the trace.

Syntax

HRESULT GetWrittenRegister(
  [in]   UINT stepIndex,
  [in]   UINT writtenRegisterIndex,
  [out]  D3D11_TRACE_REGISTER *pRegister,
  [out]  D3D11_TRACE_VALUE *pValue
);

Parameters

stepIndex [in]

The index of the step within the trace. The range of the index is [0...NumTraceSteps-1], where NumTraceSteps is a member of the D3D11_TRACE_STATS structure. You can retrieve information in any step order.

writtenRegisterIndex [in]

The index of the register within the trace step. The range of the index is [0...NumRegistersWritten-1], where NumRegistersWritten is a member of the D3D11_TRACE_STEP structure.

pRegister [out]

A pointer to a D3D11_TRACE_REGISTER structure. GetWrittenRegister fills the members of this structure with information about the register that was written by the step in the trace.

pValue [out]

A pointer to a D3D11_TRACE_VALUE structure. GetWrittenRegister fills the members of this structure with information about the value that was written to the register.

Return value

GetWrittenRegister returns:

• S_OK if the method retrieves the register information.
• E_FAIL if a trace is not available or if the trace was not created with the D3D11_SHADER_TRACE_FLAG_RECORD_REGISTER_WRITES flag.
• E_INVALIDARG if stepIndex or writtenRegisterIndex is out of range or if pRegister or pValue is NULL.
• Possibly other error codes that are described in Direct3D 11 Return Codes.
