/**	Read double value from char string.
	The function temporarily resets the LC_NUMERIC locale setting
	to "C" to retrieve the number and returns the setting to the
	original value before returning.

	CRT on Windows: Required.
	@param	rp	Address of result variable.
	@param	src	String to process.
	@param	endptr	Address of pointer variable.
			A pointer to the first character not processed
			is stored here. The function may also store
			a NULL pointer here.
			The pointer variable is probably left unchanged
			on errors or if strtod()/wcstod()  is not available
			on your system (the sscanf()/swscanf() function is
			used as fallback).
	@param	atg	Allow trailing garbage:
			0=no unprocessable trailing bytes allowed,
			1=trailing whitespaces allowed,
			2=any trailing characaters allowed.
	@param	erp	Error report, may be NULL.
	@return	1 on success, 0 on error.
	
	Error codes:
	DK4_E_INVALID_ARGUMENTS	if rp or src is NULL,
	DK4_E_SYNTAX		if there are unexpected characters in the
				string,
	DK4_E_MATH_OVERFLOW	if a mathematical overflow occurs,
	DK4_E_MATH_UNDERFLOW	if a mathematical underflow occurs.
