     The start of the string. The string must be null-terminated, and may also
     include a single newline before its terminating null. The first character
     may also be a plus sign, but not a minus sign.

     The number base to use. The maximum supported base is 16. If base is
     given as 0, then the base of the string is automatically detected with the
     conventional semantics - If it begins with 0x the number will be parsed as a
     hexadecimal (case insensitive), if it otherwise begins with 0, it will be
     parsed as an octal number. Otherwise it will be parsed as a decimal.

   Returns 0 on success, -ERANGE on overflow and -EINVAL on parsing error.
