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

I was composing this perl poem and I ran into a strange issue with the kill command. I've only used it once before (Perl 5.10.0 on Ubuntu) and it worked fine, but this time, every time I try to kill ALRM, $$, the program quits. I tried kill 14, $$, same issue. I had set a signal handler for SIGALRM:

$SIG{ALRM} = sub { print "Alarming!\n"; };

...but it doesn't print. Any guesses as to what's going on here?

> perl -MConfig -e "print $Config{sig_name}" ZERO HUP INT QUIT ILL NUM05 NUM06 NUM07 FPE KILL NUM10 SEGV NUM12 PIPE + ALRM TERM NUM16 NUM17 NUM18 NUM19 CHLD BREAK ABRT STOP NUM24 CONT CLD
print pack("A25",pack("V*",map{1919242272+$_}(34481450,-49737472,6228,0,-285028276,6979,-1380265972)))

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.
