2833  rc等于0
2835  如果(sk == NULL)则返回:0
2837  如果sk_family不等于PF_INET且非IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_IPV6)或sk_family不等于PF_INET6的值则返回:0
2840  如果addrlen小于ffsetofend(TYPE, MEMBER)*@TYPE: The type of the structure*@MEMBER: The member within the structure to get the end offset of(structsockaddr, sa_family)则返回:0
2842  如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_IPV6)且address family, AF_xxx 恒等于IP version 6 则
