im just creating an client that is going to communicated with Iterative server.
and i get this error:
warning: the `gets' function is dangerous and should not be used.
and i think this is related to this code:
printf("Enter message to be sent:\n");
gets(send_buf);
and this is my code for the client could anyone could check it to see if am on the right track:
