Using accept() and select() at the same time?

Question

I\'ve got an event-driven network server program. This program accepts connections from other processes on other hosts. There may be many short-lived connections from diff

Answer 1

you could use listen then use select or poll then accept

if (listen(socket_fd, Number_connection) < 0 )
{
    perror("listen");
    return 1;
}
fd_set set;
struct timeval timeout;
int rv;
FD_ZERO(&set); /* clear the set */
FD_SET(socket_fd, &set); /* add our file descriptor to the set */

timeout.tv_sec = 20;
timeout.tv_usec = 0;

rv = select(socket_fd + 1, &set, NULL, NULL, &timeout);
if (rv == -1)
{
    perror("select"); /* an error occurred */
    return 1;
}
else if (rv == 0)
{
    printf("timeout occurred (20 second) \n"); /* a timeout occurred */
    return 1;
}
else
{
    client_socket_fd = accept (socket_fd,(struct sockaddr *) &client_name, &client_name_len);
}
