non blocking read

Hi,

considering this simple perl example:

my %env;
my $in = new IO::Handle;
my $out = new IO::Handle;
my $err = new IO::Handle;
my $req = FCGI::Request($in, $out, $err, \%env);
while($request->Accept() >= 0)
{
...

How can I do a non blocking read on $in ?

There is an error with fileno($in) , so I cannot use select().

Thank you for your help
Sebastian
