struct sockaddr_un结构有两个参数:sun_family、sun_path。sun_family只能是AF_LOCAL或AF_UNIX,而sun_path是本地文件的路径。通常将文件放在/tmp目录下。例如: structsockaddr_un sun; sun.sun_family=AF_LOCAL; strcpy(sun.sun_path, filepath); bind(sockfd, (structsockaddr*)&sun,sizeof(sun)); 监听 ...

strcpy(un.sun_path, "foo.socket"); if ((fd = socket(AF_UNIX, SOCK_STREAM, 0)) < 0) { perror("socket error"); exit(1); } size = offsetof(struct sockaddr_un, sun_path) + strlen(un.sun_path); if (bind(fd, (struct sockaddr *)&un, size) < 0) { perror("bind error"); ...
POSIX没有定义sun_path的大小,而且明确警示应用程序不应该假设一个特定长度。所以应用程序在运行时要使用sizeof得到本结构的长度,再验证一个路径名是否适合存放到sun_path中(数组长度很可能在92到108之间) 如果sun_path是一个空字符串:那么绑定此结构体的域套接字地址等价于IPV4的INADDR_ANY常值或者IPV6的...
un.sun_family = AF_UNIX; strcpy(un.sun_path, "foo.socket"); if ((fd = socket(AF_UNIX, SOCK_STREAM, 0)) < 0) { perror("socket error"); exit(1); } size = offsetof(struct sockaddr_un, sun_path) + strlen(un.sun_path); ...
Linux网络编程之sockaddr与sockaddr_in,sockaddr_un结构体详细讲解 sockaddr struct sockaddr { unsigned short sa_family; /* address family, AF_xxx */ char sa_data[14]; /* 14 bytes of protocol address */ };sa_family是地址家族，一般都是“AF_xxx”的形式。好像通常大多用的是都是AF_IN...
