主函数（）

 int clilen - sizeof(servaddr)
    
    getsockname(sockfd, (struct sockaddr*) &servaddr, clilen)
    
    
    printf()
    
    
    int variable
    
    "int variable = getsockname(syntaxfunction)"

我应该如何为 getsockname() 函数初始化我的变量？

在初始化getsockanme之前我应该​​有int变量声明吗？

我最终将如何将我的变量应用到 printf() 以打印套接字：端口字符串？

int clientsock, clicnnct;


clientsock = socket( PF_INET, AF_INET, 0 );




struct sockaddr_in clientserv;


clientserv.sin_family = AF_INET;
clientserv.sin_addr.s_addr = htonl(INADDR_ANY);
clientserv.sin_port = htons(8980);
memset( &clientserv, 0, sizeof(clientserv) );




clicnnct = connect ( clientsock, (struct sockaddr *)&clientserv, sizeof(clientserv ) );



int  cliapi;
  

  
  
cliapi - getsockname(clientsock, (struct sockaddr*)&clientserv,
                sizeof(clientserv) );
                     
                     
                
printf("%d/n",cliapi);      
                
  
                    



send(clientsock, (struct sockaddr*)&clientserv, sizeof(clientserv), 0 );

recv(clientsock, (struct sockaddr*)&clientserv, sizeof(clientserv), 0 );
