NAME

IO::Statistics - Transparently perform statistics on IO handles

SYNOPSIS

use IO::Statistics;

my ($read, $write) = (0, 0);
IO::Statistics->count (\$read, \$write, \*STDOUT);

# alternatively:
my $ios = IO::Statistics->new (\$read, \$write);
$ios->via (\*STDOUT);

print "fooo";
print "bkzlfdlkf\n";

END {
   print "read $read bytes read, wrote $write bytes\n";
}

DESCRIPTION

This module allows you to count IO activity on a file handle transparently.

BUGS

Using this IO layer on a global filehandle might result in segfault on perl_destruct.
