( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I wrote sample code of thread control using signaling as advised by monks. As below, but the thread didn't exit when Ctrl+c pressed:
#/usr/bin/perl -w use strict; use warnings; use threads; use threads::shared; my @thrList; my $count=1; share $count; $SIG{INT} = \&catch_CtrlC; &main; sub main { my $counter = 3; while($counter) { $counter--; my $thrHandle = threads->create(\&thrdfun); push @thrList, $thrHandle; } print " waiting \n"; foreach(@thrList){ $_->join(); } } sub thrdfun { $SIG{INT} = \&trExit; print "thrdfun: $count \n"; $count++; while(1){ } exit; } sub trExit { print " exit \n"; threads->exit(); } sub catch_CtrlC { print " catch_CtrlC \n"; foreach(@thrList){ $_->kill("INT"); } exit; }
In my plan, catch_CtrlC will first receive the signal and forward it to all thread one by one. For every thread, the trExit will do sth. and exit. I guess I'm using in a wrong way, righ?

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.
