User Contributed Perl Documentation IO(3) NAME Tk::IO - high level interface to Tk's 'fileevent' mechanism SYNOPSIS my $fh = Tk::IO->new(-linecommand => callback, -childcommand => callback); $fh->exec("command") $fh->wait $fh->kill WARNING INTERFACES TO THIS MODULE MAY CHANGE AS PERL'S IO EVOLVES AND WITH PORT OF TK4.1 DESCRIPTION Tk::IO is now layered on perl's IO::Handle class. Interfaces have changed, and are still evolving. In theory C methods which enable non-blocking IO as in earlier Tk-b* release(s) are still there. I have not changed them to use perl's additional Configure information, or tested them much. Assumption is that exec is used to fork a child process and a callback is called each time a complete line arrives up the implied pipe. "line" should probably be defined in terms of perl's input record separator but is not yet. The -childcommand callback is called when end-of-file occurs. $fh->wait can be used to wait for child process while processing other Tk events. $fh->kill can be used to send signal to child process. BUGS Still not finished. Idea is to use "exec" to emulate "system" in a non-blocking manner.
