函数名称：moyo_write_group - Write "struct tomoyo_path_group"/"struct tomoyo_number_group"/"struct tomoyo_address_group" list.*@param: Pointer to "struct tomoyo_acl_param".*@type: Type of this group.* Returns 0 on success, negative value otherwise.

函数原型：int tomoyo_write_group(struct tomoyo_acl_param *param, const u8 type)

返回类型：int

参数：

类型参数名称
struct tomoyo_acl_param *param
const u8type
76  group等于moyo_get_group - Allocate memory for "struct tomoyo_path_group"/"struct tomoyo_number_group".*@param: Pointer to "struct tomoyo_acl_param".*@idx: Index number.* Returns pointer to "struct tomoyo_group" on success, NULL otherwise.
77  error等于负EINVAL
79  如果非group则返回:负ENOMEM
81  list等于member_list
82  如果type恒等于TOMOYO_PATH_GROUP则

86  如果非member_name则
87  error等于负ENOMEM
88  转到:out
90  error等于moyo_update_policy - Update an entry for exception policy.*@new_entry: Pointer to "struct tomoyo_acl_info".*@size: Size of @new_entry in bytes.*@param: Pointer to "struct tomoyo_acl_param".*@check_duplicate: Callback function to find duplicated entry.
92  moyo_put_name - Drop reference on "struct tomoyo_name".*@name: Pointer to "struct tomoyo_path_info". Maybe NULL.* Returns nothing.
93  否则如果type恒等于TOMOYO_NUMBER_GROUP则
94  struct tomoyo_number_group e = {}
96  如果data[0]恒等于'@'或非tomoyo_parse_number_union(param, & number)则转到:out

105  否则
106  struct tomoyo_address_group e = {}
108  如果data[0]恒等于'@'或非tomoyo_parse_ipaddr_union(param, & Structure for holding an IP address. )则转到:out
