函数名称：moyo_init_request_info - Initialize "struct tomoyo_request_info" members.*@r: Pointer to "struct tomoyo_request_info" to initialize.*@domain: Pointer to "struct tomoyo_domain_info". NULL for tomoyo_domain().*@index: Index number of functionality.

函数原型：int tomoyo_init_request_info(struct tomoyo_request_info *r, struct tomoyo_domain_info *domain, const u8 index)

返回类型：int

参数：

类型参数名称
struct tomoyo_request_info *r
struct tomoyo_domain_info *domain
const u8index
1002  memset(r, 0, r的长度)
1003  如果非domain则domain等于moyo_domain - Get "struct tomoyo_domain_info" for current thread.* Returns pointer to "struct tomoyo_domain_info" for current thread.
1005  domain等于domain
1006  profile等于 Profile number to use.
1007  profile等于profile
1008  type等于index
1009  One of tomoyo_mode_index . 等于moyo_get_mode - Get MAC mode.*@ns: Pointer to "struct tomoyo_policy_namespace".*@profile: Profile number.*@index: Index number of functionality.* Returns mode.
1010  返回:One of tomoyo_mode_index .
