( [id://3333] : superdoc . print w/replies, xml ) Need Help??

Note that flock() under Win32 is more like the (non-default) mandatory locking in Unix than like regular advisory locking.

This means that having a lock on a file in Win32 can prevent other processes from reading from or writing to the file (I used to think it even prevented opening but my current testing says otherwise so this might depend on the version of Win32 or...).

What you might find even more surprising is that having a lock on one file handle can prevent the same process from reading from or writing to that file via a different file handle.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
