working with files

[Miststlkr]

Hey guys, It's been a while but I'm trying to use C++ again. i used to know it prety well but it's been a few years and I am drawing a blank on some things.

I remember with pascal there was a dos.tpu that let you use functions that immitated DOS commands (more like unix commands) by typing chdir(dir_name) and a findfirst(file_name) would return the first alphabetized filename, then find_next(file_name) to move down the list and you could write a function that would print the filenames in a directory, or whatever. also, rename files, mkdir() to make a new directory, etc.

I remember there being something similar in C++ but can't remember what it was. anyone have any help or know where i might look for it?

Hmm... this isn't C++, but on *nix systems there are opendir(), readdir(), scandir(), seekdir() and closedir().
opendir() returns a DIR*, which readdir() (and the other functions) uses to see which files are placed in the opened directory. And in case, if the filename is another directory.. So I guess with a few loops you could walk through an entire directory structure, based on the file types found in matching directories.

yeah, pascal had procedures that did it from within a program, i'm trying to find the equivelent procedures in C++. i'm sure they exist, i just can't remember them on the bright side, i should have a *nix box again at the end of this month if all goes well... which it never does
