Detailed Description

Class that reads a sample stream from a Unix FIFO.

This class supports the following properties:

.filename - the path to the input file

• may be overridden by the -signal_source or -s command-line arguments

.sample_type - data type read out from the FIFO. default ishort ;

• note: not output format. that is always gr_complex

.dump - whether to archive input data

.dump_filename - if dumping, path to file for output
