in thread File Locking

And what do you think truncate(MYFILE,0) does?

How can you just ignore that part?

    truncate FILEHANDLE,LENGTH
    truncate EXPR,LENGTH
            Truncates the file opened on FILEHANDLE, or named by EXPR, to
            the specified length. Produces a fatal error if truncate isn't
            implemented on your system. Returns true if successful, the
            undefined value otherwise.

    His point is still valid. The seek command brings you to the beginning and the description say it brings you to the end. Don't be a jerk.

      The description says

      seek(MYFILE, 0, 0); truncate(MYFILE, 0);
      These bring us to the end of the file, and then sets the length to zero.
      It describes what happens in effect, not how (it doesn't say seek brings us to the end of the file and truncate sets the length to zero).

      Besides, what is the end of a zero length file? The beginning
