When you spawn a child from the parent, the parent blocks. So in
use IPC::Run3 qw( run3 );
my @cmd = qw( slow_thingy.pl );
run3 [EMAIL PROTECTED], \$in, \$out, \$err;
, the call to run3() does not return until slow_thingy.pl exits and if
you use CODE refs (instead of SCALAR refs) for redirecting
slow_thingy.pl's console I/O, they won't be called until slow_thingy.pl
exit()s. So you can't interact
This differs from IPC::Run::run() where you can use CODE refs for
stdout/stderr redirection and interact with the child process by having
your stdout/stderr handlers feed input back in to the child process via
its stdin.
That's all.
