readline <STDIN> without waiting.
Exists any way to readline enter in a loop when enter in STDIN input.
I need a input but not depends a user entry to program continue
running.
It`s also like something to tkRunning(1) BUT to <STDIN> :)
"tkRunning - makes Tk event loop run when waiting for user input
(i.e., during readline method). "
anybody knows ? :)
tks !

my $rin=``;
my $rout;
vec($rin,fileno STDIN,1)=1;
while( !select($rout=$rin, undef, undef, 0) ){
print "continue running
";
sleep 1;
}
$_ = <STDIN>;
print $_;

Do not mix buffered input (like reading <STDIN>) with select().
