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:
 $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.
