Re: [Dev-C++] List files and check if a directory exist.

[<we...@ha...>]

Hi Guys,

Thkz a lot Carlos.


>I haven't learned about it yet, but the solution is in >dirent.h, do a
search ...

Ok, i searched. But all examples that i found didn't compile.

See the example:

#include <stdio.h>
#include <dirent.h>

int main (){

DIR *dirh;

struct dirent *dirp;
static char mydir[20] = "/etc";

if ((dirh = opendir(mydir)) == NULL){

    perror("opendir");
    return(0);

}

for (dirp = readdir(dirh); dirp != NULL; dirp = readdir(dirh)){

    printf("Got dir entry: %s\n",dirp->d_name);

}

closedir(dirh);

}

When i compile i received this error:


[Linker error] undefined reference to `opendir'
[Linker error] undefined reference to `readdir'
[Linker error] undefined reference to `closedir'

What is wrong ?? How to solve it ??

Ahhh, the lib dirent.h appear that haven't a funciont to check if a
directory exist. Someone knwo other way to check ??

Thkz a lot.

Best Regards.
