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.
