    Question fork

    Hello,

    I am programming in Unix and now working with processes. I have a father process that creates some children processes that need to calculate something but I don't know how to return the result to the father process (except of returning it as the exit status which doesn't seem to me like a proper solution).
    Is there another way to do it?

    Thanks.

    Use named pipes. Use a file.

    In UNIX, pipes are the defacto standard way to do this.
