( #3333=superdoc: print w/replies, xml ) Need Help??
I'm now using the below. Anyone see any problems? Should I still use truncate($fh, 0); after seek or does the sysopen take care of that?
sub safe_open { my $fn = shift; $fn =~ s/^(>>?)//; $mode = length($1); my $flags = $mode == 1 ? O_CREAT | O_WRONLY | O_TRUNC : $mode == 2 ? O_CREAT | O_WRONLY | O_APPEND : O_RDONLY; sysopen(my $fh, $fn, $flags) or die "Can't open $fn: $!"; if ($flock_enabled) { flock($fh, LOCK_EX) or die "Can't flock $fn: $!"; } seek $fh, 0, 0; return $fh; }

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 or How to display code and escape characters are good places to start.
