    Default Accessing Environment Variables

    Hi,

    I'm trying to find a way of accessing some environment varibles. I thought I saw something somewhere in the docs about it, but I didn't see anything in QApplication.

    I hope to get out of doing a QProcess env command and searching through the results.


    Thanks!

    How about ::getenv()? It should be implemented even on windows.

    You can also use the third argument to the main() function, just remember you get a copy of environment there.

    In Windows:
    Note: getenv is deprecated; consider using getenv_s instead

    You expected MS to break the mold, right?

    Thanks !! getenv works great.

    getenv_s must be windows because I can't compile with that command.

    You folks are Qt addicts aren't you? So , how about using qgetenv() instead? It provides portability and same features as the classic getenv() ...

    The only issue about qgetenv is that it is only defined in Qt version 4.X.
