ID3D11ShaderTrace::GetReadRegister method (d3d11shadertracing.h)
Retrieves information about a register that was read by a step in the trace.
Syntax
HRESULT GetReadRegister(
[in] UINT stepIndex,
[in] UINT readRegisterIndex,
[out] D3D11_TRACE_REGISTER *pRegister,
[out] D3D11_TRACE_VALUE *pValue
);
Parameters
[in] stepIndex
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.
[in] readRegisterIndex
The index of the register within the trace step. The range of the index is [0...NumRegistersRead-1], where NumRegistersRead is a member of the D3D11_TRACE_STEP structure.
[out] pRegister
A pointer to a D3D11_TRACE_REGISTER structure. GetReadRegister fills the members of this structure with information about the register that was read by the step in the trace.
[out] pValue
A pointer to a D3D11_TRACE_VALUE structure. GetReadRegister fills the members of this structure with information about the value that was read from the register.
Return value
GetReadRegister 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_READS flag.
- E_INVALIDARG if stepIndex or readRegisterIndex is out of range or if pRegister or pValue is NULL.
- Possibly other error codes that are described in Direct3D 11 Return Codes.
