返回类型：int

参数：

类型参数名称
struct sockaddr *addr
const unsigned intaddr_len
struct tomoyo_addr_info *address
597  u等于unix0
599  如果addr_len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
601  如果address family, AF_xxx 不等于Unix domain sockets 则返回:0
603  This may not be '\0' terminated string. 等于sun_path
604  addr_len等于addr_len
605  返回:moyo_unix_entry - Check permission for UNIX network operation.*@address: Pointer to "struct tomoyo_addr_info".* Returns 0 on success, negative value otherwise.
