Multiple writes to client socket

[Daniel Draper]

Hi,

I have a written a simple client server app using sockets in c. My
client code works great for a single send/recv operation but as soon
as I try to write (send) to the same socket again the server does not
receive the data.

My client code looks like this:

sock = make_socket (PORT);

for (i = 0; i < 2; i++)
{
send(sock, MESSAGE, strlen(MESSAGE) + 1, 0);

n = recv(sock, buf, sizeof(buf), 0);
if (n > 0)
printf("server echoed %s\n", buf);
}

close(sock);

First iteration works, but second fails.

Any ideas?

Daniel

Yes. Try a newsgroup specific to your operating system (perhaps
comp.unix.programmer).

What is this sizeof ( buf ).. it might be that sizeof(buf) is much
larger than strlen(MESSAGE) so it might be w8ing to read sizeof(buf)
from the the socket.

Who knows? You haven't quoted the message you're replying to,
