The usual multi-process server would typically look something like this (pseudo-code):

passive_socket = create_listening_socket()

for (;;)
{
    new_socket = accept(passive_socket)
    if (fork() == 0)
    {
        /* In child */
        read_from_socket(new_socket)
        write_to_socket(new_socket)
        /* Or do any other processing needed */

        exit(0);
    }
    else
    {
        /* In parent */
        close(new_socket)
    }
}
