ah ha! So something like:
if (-p $named_pipe_name) { eval { local $SIG{ALRM} = sub { die "alarm\n" }; # NB: \n required alarm $timeout; if (sysopen(FIFO, $named_pipe_name, O_RDONLY)) { while(my $this_line = <FIFO>) { chomp($this_line); $result .= $this_line; } close(FIFO); } else { $errormsg = "ERROR: Failed to open named pipe $named_pipe_name + for reading: $!"; } alarm 0; }; if ($@) { if ($@ eq "alarm\n") { # timed out $errormsg = "Timed out reading from named pipe $named_pipe_nam +e"; } else { $errormsg = "Error reading from named pipe: $!"; } } else { # didn't time out print STDOUT "$result\n"; } }

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.
