    Question getting input (not from main())

    a newbie question

    I try to write a program in multiple source files, the first function should get input from commend line or a given file.
    I wonder can I have argc, argv[] as a function argument to get the command line input and let main() call it...

    Thank you.

    main() is always called first, i'm not sure if argc and argv[] are considered global to the program or local to main, but if you can't use them in another function then you can pass them to that function. Just don't change argc or argv[] or you could cause some problems.

    So you should be okay just using argc and argv[] anywhere in your program. If I'm wrong then someone will correct me ;p
