Re: [Discuss-gnuradio] saving internal (to a block) variable values to a file

[Jose Torres Diaz]

Hi, 

Also I'm saving some variables into a file. What I did:

 Before the work function:

myfile.open ("/home/Desktop/examples/variables_from_block");

Then, inside the work function:

myfile << _msg.key; //Save the variable value
myfile << std::flush; 

I've found that I have to std::flush the file, because if I close it (myfile.close()), I cannot access the file anymore and the variable is saved once only.

Hope this helps, 

Cheers, 

Jose

Well I am pretty sure that your query is more complicated than what I am
thinking, but I did the following just to check. Inside the work function of
howto_square_ff.cc

I pasted following lines

        ofstream outdata;
        int i; // loop index
        int num[5] = {4, 3, 6, 7, 12}; // list of output values
        outdata.open("/home/sumit/example2.dat");
        for (i=0; i<5; ++i)
        outdata << num[i] << std::endl;
        outdata.close();

compiled it ...

And I got them written in example2.dat

Anyways I am curious to see if you get some effective reply :)
