ID3D11ShaderTrace::GetReadRegister Method

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

Syntax

public:
HRESULT GetReadRegister(
         UINT stepIndex,
         UINT readRegisterIndex,
         D3D11_TRACE_REGISTER *pRegister,
         D3D11_TRACE_VALUE *pValue
)  

Parameters

stepIndex
Type: UINT 

[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.

readRegisterIndex
Type: UINT 

[in] 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.

pRegister
Type: D3D11_TRACE_REGISTER *

[out] 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.

pValue
Type: D3D11_TRACE_VALUE *

[out] 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

Type: HRESULT 

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.

Requirements

Header: Declared in d3d11shadertracing.h.

Library: Use d3d11.lib.
