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 ...

SUN_LEN宏: 功能:参数为一个sockaddr_un结构的指针,此宏返回此结构的长度,其中包括路径名中非空字节数 offsetof宏: 该宏可以以字节为单位,返回一个结构中指定成员在结构体中的偏移量,我们可以用该宏来判断sun_path在域套接字地址中的大小,使用案例见文章: ...

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_INET。sa_data是14字节协议地址。此数据结构用做bind、connect、rec...
