setsockopt(sockett,SOL_SOCKET,SO_REUSEADDR,&opt,sizeof(opt) );

server.sin_family=AF_INET;
server.sin_port=htons(80);
server.sin_addr.s_addr=inet_addr("127.0.0.1");

if ((bind(sockett,(struct sockaddr *) &server,sizeof(server))) != 0)
{
printf("Bind failed\n");
}

else
printf("Bind success\n");

if ((listen(sockett,5)) < 0)
{
printf("Listen failed\n");
}

else
printf("Listen success\n");

len=sizeof(connstorage);

if(conn=accept(sockett,(struct sockaddr *)&connstorage,&len) > 0)
{
printf("Accepted\n");
}
else
printf("Notaccepted\n");

if(recv(conn, rcvmsg, 1024,0 ) < 0)
{
printf("RCV_PROBLLEM\n");
printf("%d\n",errno);
printf("err desc: %s\n",strerror(errno));
}
