Re: [Discuss-gnuradio] fifo / file source

[ali mokdad]

Thx for your reply

"it's not quite certain which program you run in that terminal" 

I just wrote cat > in

even I run a .c file in the .c file I opened a file and the data are not sent only when I close the file.

do you know a special program I can test?

Hi Ali,

it's not quite certain which program you run in that terminal, but:
File I/O is usually buffered, and this sounds like the data is never
written to your FIFO before you exit your terminal program.

Solution: Use a terminal program that doesn't buffer or flushes
regularly.

Best regards,
Marcus
