Hi,
look at the following code:
The client after estabilishing a connection with the server does the following:
if ((peter = fopen(argv[1], "r")) == NULL){
printf("errore\n");
exit(0);
}

send_file(peter, sockfd); /* transfers the file to the server */
fclose(peter);
printf("File spedito\n");

read(sockfd, (char *) &res, sizeof(res)); /* here it waits for a receipt */
res = ntohs(res);
if(res == RECEIPT)
printf("RECEIPT received\n");
else
printf("RECEIPT not received\n");

close(sockfd);
}

The server after accepting the connection does the following:
if ((fp = fopen("transazione", "w")) == NULL){
printf("errore\n");
exit(0);
}
get_file(fp, connfd); /* obtain the file from the client */
fclose(fp);
printf("File received\n");

shutdown(connfd, SHUT_RD);
res = htons(RECEIPT);
writen(connfd, (char *) &res, sizeof(res));
printf("RECEIPT sent\n");
}
The whole program compile but when I try to execute it the client acrtually send the file and blocks on the read call on the socket and the server bloks on the get file function, never returning? Anyone can help?
By the way the two function get_file and send_file read from the socket and write to the file(get_file) or the opposite(read from the file e write to the socket, send_file)
Thanx in advance!!!
