一个win32平台的socket简单程序

最新学习了下win32平台以及linux平台的socket程序编写,发现2者的差别不是很大,就是传输数据的时候调用的函数不同 基本流程都是大同小异,下面贴下自己写的一个比较简单的socket程序,

 

服务器端:

#include
#include


int main()
{
  WORD wVersionRequested;
  WSADATA wsaData;
  int err;
    
  wVersionRequested = MAKEWORD( 1, 1 );
    
  err = WSAStartup( wVersionRequested, &wsaData );
  if ( err != 0 ) {
    return 1;
  }
    
  if ( LOBYTE( wsaData.wVersion ) != 1 ||
                HIBYTE( wsaData.wVersion ) != 1 )    
  {                                                                
    WSACleanup( );
    return 1;    
  }
        
        SOCKET socket_srv = socket(AF_INET,SOCK_STREAM,0);
  struct sockaddr_in        soc_addrs,soc_addrc ;
  int    soc_lens = sizeof(sockaddr);
  int    soc_lenc = sizeof(sockaddr);
  char buffer[100];
        soc_addrs.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
  soc_addrs.sin_family = AF_INET;
  soc_addrs.sin_port = htons(6000);
  bind(socket_srv,(SOCKADDR *) &soc_addrs,soc_lenc);
  listen(socket_srv,10);
  while ( 1 )
  {
    SOCKET socket_client = accept(socket_srv,(SOCKADDR*)&soc_addrc,&soc_lenc);
    recv(socket_client,buffer,100,0);
    printf("%s\n",buffer);
                closesocket( socket_client);
  }

  WSACleanup();
     return 0;
}

 

 

客户端:

#include
#include


int main()
{
  WORD wVersionRequested;
  WSADATA wsaData;
  int err;
    
  wVersionRequested = MAKEWORD( 1, 1 );
    
  err = WSAStartup( wVersionRequested, &wsaData );
  if ( err != 0 ) {
    return 1;
  }
    
  if ( LOBYTE( wsaData.wVersion ) != 1 ||
                HIBYTE( wsaData.wVersion ) != 1 )    
  {                                                                
    WSACleanup( );
    return 1;    
  }
        
  struct sockaddr_in    sco_addr;
  int len = sizeof(SOCKADDR);
  char buffer[100] = {"welcome to http://wiliiwin.cublog.cn/"};
  sco_addr.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
  sco_addr.sin_family = AF_INET;
  sco_addr.sin_port = htons(6000);
        SOCKET scoke_client = socket(AF_INET,SOCK_STREAM,0);
  while (1)
  {
    connect(scoke_client,(SOCKADDR*)&sco_addr,len);
            send(scoke_client,buffer,100,0);
    closesocket(scoke_client);
  }
  WSACleanup();
  return 0;
}

 

此程序就是客户端向服务器端发送一个字符串,服务端会接收到这个字符串,服务端要是现实出接受的字符串,就说明程序已经实现了网络通信.
