IDebugExpressionEvaluator::Parse

  • Article

This method converts an expression string to a parsed expression.

HRESULT Parse( 
   LPCOLESTR                upstrExpression,
   PARSEFLAGS               dwFlags,
   UINT                     nRadix,
   BSTR*                    pbstrError,
   UINT*                    pichError,
   IDebugParsedExpression** ppParsedExpression
);

int Parse(
   string                     upstrExpression, 
   enum_PARSEFLAGS            dwFlags, 
   uint                       nRadix, 
   out string                 pbstrError, 
   out uint                   pichError, 
   out IDebugParsedExpression ppParsedExpression
);

Parameters

  • upstrExpression
    [in] The expression string to be parsed.

  • dwFlags
    [in] A collection of PARSEFLAGS constants that determine how the expression is to be parsed.

  • nRadix
    [in] Radix to be used to interpret any numerical information.

  • pbstrError
    [out] Returns the error as human-readable text.

  • pichError
    [out] Returns the character position of the start of the error in the expression string.

  • ppParsedExpression
    [out] Returns the parsed expression in an IDebugParsedExpression object.

Return Value

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

Remarks

This method produces a parsed expression, not an actual value. A parsed expression is ready to be evaluated, that is, converted to a value.
