其中,SOCKET结构体用于表示一个socket连接。sockaddr_in表示一个地址结构,用它来保存需要连接的主机ip地址及端口号,或者是需要监听的端口号。 客户端基本流程图如下图: 服务器基本流程图如下: 这次实现的功能主要是:客户端向服务器发送一个字符串和一个文件(图片文件),服务器以接收到的字符串为文件名,并将接收到...
int bind( SOCKET s, const struct sockaddr FAR *name,int namelen ); 参数说明 s:server端已经创建好的SOCKET name:server的SOCKADDR_IN结构,需要做强制类型转换,注意,他和SOCKADDR的大小一样 namelen:顾名思义,name的size大小,注意他和SOCKADDR的大小一样 作用 将SOCKET绑定到机器上 返回值 成功返回0,错误返...
In the Internet address family, this structure is used by Windows Sockets to specify a local or remote endpoint address to which to connect a socket. This is the form of the sockaddr structure specific to the Internet address family and can be cast to sockaddr....
int bind(SOCKET s, const struct sockaddr * name,int namelen); SOCKET: 即 socket 描述字,它是通过 socket() 函数创建了,唯一标识一个 socket。bind() 函数就是将给这个描述字绑定一个名字。 sockaddr: 一个 const struct sockaddr *指针,指向要绑定给 sockfd 的协议地址。 namelen: 对应的是地址的长度。

[in] SOCKET s, [in] const sockaddr *name, [in] int namelen ); 参数 [in] s 标识未绑定套接字的描述符。 [in] name 指向要分配给绑定套接字 的本地地址 的 sockaddr 结构的指针。 [in] namelen name 参数指向的值的长度(以字节为单位)。
