[Click] Help, about handler

[wubaochuan]

Hi Beyers,
     Thank you.
     I have tried an example, but I always failed to connect to 
ControlSocket.
     I use test.click and client.c, after run *click test.click*, I 
compile client.c, and run the client, but I always get the following 
output:connect error: Connection refused. I examine the program 
carefully, but I do not know what is wrong.
    
test.click:
//start of test.click
ControlSocket("TCP", 1234);
InfiniteSource(DATA \<00 00 c0 ae 67 ef  00 00 00 00 00 00  08 00

        -> Print(ok)
    -> Discard;
//end of test.click
=======================================================================

client.c, a very simple program, connect to
//start of client.c
#include <sys/types.h>
#include <sys/socket.h>
#include <stdio.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <unistd.h>
#include <stdlib.h>


int main()
{
    int sockfd;
    int len;
    struct sockaddr_in address;
    int result;

    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd == -1)
    {
        perror("socket() error");
        exit(1);
    }

    address.sin_family = AF_INET;
    address.sin_addr.s_addr = inet_addr("10.3.16.138"); // this is the 
machine I run click, the program generated by click.c also runs on this 
machine.
    address.sin_port = 1234;               
    len = sizeof(address);

    result = connect(sockfd, (struct sockaddr *)&address, len);

    if (result == -1)
    {
        perror("connect() error"); // it always failed, always output: 
*connect() error: Connection refused*
        exit(1);
    }

    close(sockfd);
    return 0;
}
//end of client.c


I can see click is listenning on port 1234 using following command: 
netstat -ntlp | grep 1234
But why it always fails when I connect to this port ? Is there an 
example can tell me how a client can connect to click's controlsocket ?
Thank you.
