        struct stat mystat;

            logfile = freopen(logfilename, "a+", logfile);
            inode = mystat.st_ino;
        }

        while (stuff_in_buffer)
        {
            fwrite(); /* etc */
        }
        fflush(logfile);

        /* sleep until something interesting happens */
    }
}

或者 rename 加 freopen
