There are many examples in the python files. Look into the logging section of any modulator/demodulator code.
If you are reading or writing complex data use these gr.file_source(gr.sizeof_gr_complex,"filename") gr.file_sink(gr.sizeof_gr_complex,"filename") The first argument is the sizeof(datatype stored in the file). It can be char, gr_complex, int, float . You can read these files using the utility programs in gnuradio-core/src/utils On Mon, May 3, 2010 at 5:41 AM, Umair Naeem <ar...@student.chalmers.se>wrote: > I need to know how are File source and file sink used.
