参数：

类型参数名称
const char *s
unsigned intbase
unsigned long long *res
301  s等于_parse_integer_fixup_radix(s, & base)
302  rv等于Convert non-negative integer string representation in explicitly given radix* to an integer.* Return number of characters consumed maybe or-ed with overflow bit.* If overflow occurs, result integer (incorrect) is still returned.
303  如果rv按位与KSTRTOX_OVERFLOW则返回:负ERANGE
305  如果rv恒等于0则返回:负EINVAL
307  s加等于rv
308  如果s恒等于'\n'则s自加
310  如果s则返回:负EINVAL
