函数名称：moyo_parse_ipaddr_union - Parse an IP address.*@param: Pointer to "struct tomoyo_acl_param".*@ptr: Pointer to "struct tomoyo_ipaddr_union".* Returns true on success, false otherwise.

函数原型：bool tomoyo_parse_ipaddr_union(struct tomoyo_acl_param *param, struct tomoyo_ipaddr_union *ptr)

返回类型：bool

参数：

类型参数名称
struct tomoyo_acl_param *param
struct tomoyo_ipaddr_union *ptr
53  min等于u6_addr8
54  max等于u6_addr8
55  address等于tomoyo_read_token(param)
58  如果非strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for且in4_pton(address, - 1, min, '-', & end)大于0则
60  Valid only if @group == NULL. = false
61  如果非end则s6_addr32[0]等于s6_addr32[0]
63  否则如果end自加不等于'-'或in4_pton(end, - 1, max, '\0', & end)小于等于0或end则返回:false
66  返回:true
68  如果in6_pton(address, - 1, min, '-', & end)大于0则
69  Valid only if @group == NULL. = true
70  如果非end则memmove(max, min, sizeof(u16) * 8)
72  否则如果end自加不等于'-'或in6_pton(end, - 1, max, '\0', & end)小于等于0或end则返回:false
75  返回:true
77  返回:false
