Class Netchannels.lift_rec_in_channel

This class implements pos_in and the methods from compl_in_channel * by calling the methods of rec_in_channel. * There is no additional buffering. * * The performance of the method input_line is very bad (consider * to override it, e.g. by enhanced_input_line as defined below). * * The method pos_in is implemented by counting the number of octets * read by the input method. * *
