+/** 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.
+ @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.
