NAME
IO::Sockatmark - Perl extension for TCP urgent data
SYNOPSIS
use IO::Sockatmark;
use IO::Socket;
my $sock = IO::Socket::INET->new('some_server');
$sock->read(1024,$data) until $sock->atmark;
DESCRIPTION
This module adds the atmark() method to the standard IO::Socket class.
This can be used to detect the "mark" created by the receipt of TCP
urgent data.
Methods
$flag = $socket->atmark()
The atmark() method true if the socket is currently positioned at
the urgent data mark, false otherwise.
Exported functions
$flag = atmark($socket)
The atmark() function returns true if the socket is currently
positioned at the urgent data mark, false otherwise. This will work
with an IO::Socket object, as well as with a conventional filehandle
socket.
