[asterisk-dev] How to terminate allocated socket resource when channel hangs up!

[ast guy]

Hi,
 In my asterisk application app_myApplication() code, I have to bind a
socket to a dynamic port number, so that I can send/receive some strings. I
am able to get it working by below code.

Now the problem is; say the read timeout of socket is 60 secs and user hangs
up the channel in 30 seconds, Call is disconnected but still
app_myApplication() remains for that channel and when 60 seconds have
passed. Then normal application follow is executed and channel closes
gracefully.

Is there any way that I can terminate the socket along with channel hangup
event ?

///------------------------------ CODE
-----------------------------------------
    int sockfd, new_fd;  // listen on sock_fd
    struct sockaddr_in my_addr;    // my address information
    struct sockaddr_in their_addr; // connector's address information
    socklen_t sin_size;

    struct timeval tv;

    if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
        return -1;
    }

    my_addr.sin_family = AF_INET;         // host byte order
    my_addr.sin_port = htons(atoi(port));     // short, network byte order
    my_addr.sin_addr.s_addr = INADDR_ANY; // automatically fill with my IP
    memset(my_addr.sin_zero, '\0', sizeof my_addr.sin_zero);

    if (bind(sockfd, (struct sockaddr *)&my_addr, sizeof my_addr) == -1) {
        return -1;
    }

    if (listen(sockfd, BACKLOG) == -1) {
        return -1;
    }

// HERE I am setting the socket Read time out

    tv.tv_sec = 60;
    tv.tv_usec = 0;

    if (setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, &tv, sizeof tv) == -1) {
        return -1;
    }
