Reading in filenames

[willc0de4food]

hey, i was just wondering how i would go about reading in the files in a certain directory (the same dir that the prog is running in) of a certain type. while ripping my (legal) cd's to my computer, the program i use (CDex) adds like: 01-bandname _ songname.mp3
i think. but yea.. windows xp, dev-c++ 4.9.2. thanks

hmm...i wrote a program which suites my needs. you can find the source here: http://www.angelfire.com/droid/willc...ource/rename.c

but it would be really nice to know how to make a list of the filenames in a dir in C rather than using the system() & DOS commands, lol

thanks
mm..on the first example, which is claimed to be provided by you, i get errors on my compiler :-[

Compiler: Default compiler
Executing gcc.exe...
gcc.exe "C:\Dev-Cpp\projects\finder.c" -o "C:\Dev-Cpp\projects\finder.exe" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"

any ideas why? mm..the next example works, but i'll have to see if i can modify it for my needs.

thanks

Well, it can't find the structure

struct ffblk  finder;

and some other things. Try this (it works in Dev-C++)

#include <unistd.h>

void list(void) {
    DIR *dir;
    struct dirent *d;

    dir = opendir(".");  /* path to open */

    while(d = readdir(dir)) {
        puts(d->d_name);
    }

    closedir(dir);
}

All from memory. You should check the return value of opendir(), too.

[edit]
Or try the *NIX example in the FAQ. It's better than mine.

lol i am using the *nix example from the faq.

So does it work?

[willc0de4food]

yes, it makes a list of the filenames in the dir. but i can't filter out just the filenames w/the .mp3 extension. idk why, but its not working lol

h = FindFirstFile("*.*", &info);
becomes
h = FindFirstFile("*.mp3", &info);

I suspect you're going to starve.

h = FindFirstFile("*.*", &info);
becomes
h = FindFirstFile("*.mp3", &info);

Apparently, you can give a man some source code, but you can't make'm think.
