IDiaStackWalkHelper3::put_registerValue

Sets the value of the specified register.

Syntax

HRESULT put_registerValue(
    DWORD index,
    DWORD cbData,
    const BYTE* pbData
);

Parameters

index

[in] A value from the CV_HREG_e enumeration specifying which register to modify. This parameter value is primarily intended for the ARM64 SVE registers.

cbData

[in] Size, in bytes, of the data pointed to by pbData.

pbData

[in] Buffer containing the new register value.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

Allows modifying register values during stack walking, for example, to support unwinding or simulating execution state.

Supports variable-sized registers, including large vector registers such as ARM64 SVE.

For registers 64-bits or less (for example, 1-8 bytes), use get_registerValue and put_registerValue in IDiaStackWalkHelper.
