函数名称：转换字符串为无符号长整形

函数原型：unsigned long long simple_strtoull(const char *cp, char **endp, unsigned int base)

返回类型：unsigned long long

参数：

类型参数名称
const char *cp
char **endp
unsigned intbase
68  cp等于_parse_integer_fixup_radix(cp, & base)
69  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.
71  cp加等于rv按位与KSTRTOX_OVERFLOW的反
73  如果endp则endp等于cp
76  返回:result
