Re: [Discuss-gnuradio] File Source and FIle Sink

[Mir M. Ali]

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

I need to know how are File source and file sink used. I am trying to use file sink to store samples that can be read into number sink but when i use file source to read the same file and try to read that data to number sink it shows None in the numbe sink. Is there any file extension problem or what?
