In the tchrists broilerplate i found this explicit closing of STDOUT in the END block.
END { close STDOUT }
I know END and close, but i'm missing why it is needed.
When start searching about it, found in the perlfaq8 the following:
For example, you can use this to make sure your filter program managed to finish its output without filling up the disk:
END {
close(STDOUT) || die "stdout close failed: $!";
}
and don't understand it anyway. :(
Can someone explain (maybe with some code-examples):
- why and when it is needed
- how and in what cases can my perl filter fill up the disk and so on.
- when things getting wrong without it...
- etc??
