多种语言socket编程集锦—win32

借此地方整理以下socket编程的多种语言的实现，socket可以跨平台的通信，因此多语言、多平台下的实现有必要了解的。代码都是源自网上，感谢网友的分享。

socket编程在windows下的C语言实现，dev C++下编译通过
编译时设置编译选项 工具-->编译选项-->编译器，勾选在连接器命令行加入以下命令，在对话框中填-lwsock32
//server.c
#include <stdio.h>
#include <Winsock2.h>
int main()
{
WORD wVersionRequested;
WSADATA wsaData;
int err;

wVersionRequested = MAKEWORD( 1, 1 );

err = WSAStartup( wVersionRequested, &wsaData );
if ( err != 0 ) {
return;
}

if ( LOBYTE( wsaData.wVersion ) != 1 ||
HIBYTE( wsaData.wVersion ) != 1 ) {
WSACleanup();
return;
}
SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);

SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
addrSrv.sin_family=AF_INET;
