Thanks for that code example! Passing a filehandle through a thread shared variable was something I've been searching for for awhile. Just for demonstration purposes, it can go the other way too.....create the filehandle in the thread, and read it in main.
#!/usr/bin/perl use warnings; use strict; use threads; use threads::shared; my %shash; #share(%shash); #will work only for first level keys my %hash; share ($shash{'go'}); share ($shash{'fileno'}); share ($shash{'pid'}); share ($shash{'die'}); $shash{'go'} = 0; $shash{'fileno'} = -1; $shash{'pid'} = -1; $shash{'die'} = 0; $hash{'thread'} = threads->new(\&work); $shash{'go'} = 1; sleep 1; # cheap hack to allow thread to setup my $fileno = $shash{'fileno'}; open (my $fh, "<&=$fileno") or warn "$!\n"; while ( <$fh> ){ print "In main-> $_"; } #wait for keypress to keep main thread alive <>; # control-c to exit ################################################################## sub work{ $|++; while(1){ if($shash{'die'} == 1){ goto END }; if ( $shash{'go'} == 1 ){ my $pid = open(FH, "top -b |" ) or warn "$!\n"; my $fileno = fileno(FH); print "fileno->$fileno\n"; $shash{'fileno'} = $fileno; $shash{'go'} = 0; #turn off self before returning }else { sleep 1 } } END: } #####################################################################

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.
