在linux环境下,结构体struct sockaddr_in在/usr/include/netinet/in.h中定义,具体如下: /* Structure describing an Internet socket address. */ struct sockaddr_in { __SOCKADDR_COMMON (sin_); in_port_t sin_port; /* Port number. */ struct in_addr sin_addr; /* Internet address. */ /* Pa...
struct sockaddr是通用的套接字地址,而struct sockaddr_in则是internet环境下套接字的地址形式,二者长度一样,都是16个字节。二者是并列结构,指向sockaddr_in结构的指针也可以指向sockaddr。一般情况下,需要把sockaddr_in结构强制转换成sockaddr结构再传入系统调用函数中。 下面是struct sockaddr_in中用到两个数据类型,具体...
一、域套接字地址(struct sockaddr_un) 域套接字是在同一计算机的不同进程中进行通信,但是不采用IP地址和端口进行通信。内核提供了此结构体,用于为域套接字绑定文件名来绑定地址,从而实现不同域套接字之间的通信 #include <sys/un.h> //Linux和Solaris中: structsockaddr_un { sa_family_tsun_family;/*AF_...
sockaddr_in(在netinet/in.h中定义): struct sockaddr_in { short int sin_family; /* Address family */ unsigned short int sin_port; /* Port number */ struct in_addr sin_addr; /* Internet address */ unsigned char sin_zero[8]; /* Same size as struct sockaddr */ }; struct in_addr ...

Struct sockaddr structsockaddr { unsignedshortsa_family;/*address family, AF_xxx*/ charsa_data[14];/*14 bytes of protocol address*/ }; sa_family是地址家族,一般都是“AF_xxx”的形式。通常是AF_INET。 sa_data是14字节协议地址。 此数据结构用做bind、connect、recvfrom、sendto等函数的参数,指明地...

That seems awefully un-useful. What if you want your data containers to be flexable to fit your data? I haven't used C++ in a long time and I'm trying to write this program in the most simplistic non abstract way as possible. Here is the code:...
