Programming

I'm having trouble when running a program that uses the connect(). I keep receiving errno: 22. Below is the code that I am using.

Do I have the variables set up correctly?

Am I passing the correct parameters?

I have been searching for source code on the connect function but haven't found any. IF you know of some posted on the net I would really appreciate it.

-------------------------------------------------------------------------
int read_sold(char rxfile[], char message[])
{
int i, rc, s;
char hostname[64];
char readbuff[MAXREAD];
struct sockaddr_in sin;
struct sockaddr const fin;

memset(readbuff, 0, MAXREAD);
/*
*** Get TCP address and socket
*/
for (i = 0; i < 3; i++){
if (tcpaddress(&s, POSTORXPORT, &sin, (sizeof(sin)), message) == 0)
break;
if (i == 2) return -1;
}

/*
*** Try to connect to the address
*/
for (i = 0; i < 3; i++) {
if (connect(s, &fin, sizeof(fin)) < 0) {
if (i == 2) {
sprintf(message, "Client CONNECT failed: errno = %d",
errno);

No, that's all wrong. s has to be a socket to start with. That is, it should have been returned by a call to socket(). And fin needs to have the ip address and port number in it.

Rather than looking at the source code for connect(), you might want to look for a network programming tutorial.

Here is one tutorial.
