Thread: data read zeros?

  1. #1

    Question data read zeros?

    When I read in a data file that is being written to by another program, do I have to wait unitl it is done writing to display the data? Or could I display the data as it is being writen? Currently I can read a portion of the written file correctly, but it stops and prints out zeros when the data file is still being written to with valid data.

    //program that is reading in
     float input;
       /*open data file*/
         ifstream inFile("output");
       inFile >> input;
      inFile >> input;
       data.push_back(input); //vector
      inFile >> input;

    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    Sorry - I probably confused you when I moved the other post to this board. You can ask the questions on the other thread.
