Hi Monks
For some time when i turn blocking off for a file handle that points to *STDERR,
it also turns blocking off for *STDIN. I am using perl 5.8.1 . Here is the code:
my $fhandle = IO::Handle->new(); if (!$fhandle->fdopen(*STDERR, "a")) { die("Error: Unable to open \"err\" file handle: $!\n"); } $fhandle->autoflush(1); $fhandle->blocking(0); In a: while ( <STDIN> ) { doIt($_); }
As soon as we turn blocking off for STDERR, STDIN no longer blocks.
I tried to turn blocking on for STDIN with STDIN->blocking(1),
but then STDERR now has blocking turned on.

Expecting your help
