IDiaStackWalkHelper::get_registerValue

Retrieves the value of a register.

Syntax

HRESULT get_registerValue ( 
   DWORD      index,
   ULONGLONG* pRetVal
);

Parameters

index

[in] A value from the CV_HREG_e Enumeration enumeration specifying which register to get the value from.

pRetVal

[out] Returns the current value of the register.

Return Value

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

Remarks

Despite the size of the pRetVal parameter, an implementation should store only what the register normally holds. For example, an 8-bit register holds only the lowest 8-bits of the given value. This 8-bit value is expanded to 64-bits when returned from this method.
