I'm trying to write USRP data to a FIFO and read it out using a C++
app. I can't get it to work. What I did was to type 'mkfifo myfifo'
in the shell. This is the output to ls -l myfifo.
prw-r--r-- 1 sebastiaan sebastiaan 0 2008-07-23 14:20 myfifo
I then tried to run my application, passing myfifo as a parameter.
This is the line of Python code that sets up the filesink.
self.dst = gr.file_sink(gr.sizeof_gr_complex, filename)
When I run the application, it hangs and when I press CTRL+C, I get
the following output.
myfifo: Interrupted system call
terminate called after throwing an instance of 'std::runtime_error'
what(): can't open file
Can anyone please tell me if there are any other steps to get this to work?
Thank you very much.
