/** 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.
