Flushing the Buffer

[teky]

Hello Everybody,

Is there anyway we can flush the buffer in a log file in perl.

Thanks,
Teky.

$| = 1 flushes the STDIO buffer after each write. Hope you've tried this? There's always a better way...

$| = 1;

that's sets the *current* default file handle to auto-flush -- so if you want to set anything but STDOUT to auto-flush you have to do something like

open(LF,">log_file.txt&quot || die "error, $!\n";
select(LF); $|=1; Mike

I encountered this exact same need last Wednesday. I was most comfortable using the following method, which is included as part of the standard perl distribution... also, I feel that it's a bit more indicative of the intent, rather than doing multiple selects in your code:

use IO::Handle;  

open(FILE, ">>somefile.txt");

FILE->autoflush(1);  # This is the magic.

# and then continue on with your day...

Hope this helps...

ahh -- that'd be these new-fangled objekt things that I should get around to learning....

Thank you very much.
I could now flush the Log file.
