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. AUTHOR Copyright 2001, Lincoln Stein . This module is distributed under the same terms as Perl itself.
