Re: Autoflush not possible when sleep is used?

Maybe it helps if you enable autoflushing in the print application — just kinda guessing, though...

#!/usr/bin/perl
$| = 1;
print STDERR " printing some text\n";
...
sleep 10;

Update: actually, on second thought, autoflushing should not be required here anyway, as you're printing to STDERR (which already does autoflush (is unbuffered) by default). IOW, I suppose the problem lies elsewhere...

since by default `STDOUT` is selected, setting `$\| = 1` shouldn't have an effect on printing to `STDERR`.	[reply] [d/l] [select]

yeah, you're right — I overlooked the STDERR...	[reply]

Could the problem perhaps be that I compare fileno to a descriptor which is not the one I want to find? In the IPC::Open3 manual it is written to either use a reference to a typeglob filehandle or scalars to filehandles.	[reply]
