ftw , nftw doesn't work

[Nikola <root.admin1@zg.t-com.hr>]

Hi,

I am trying to parse dir tree with ftw and nftw on Linux (debian) but 
without result.

------------------------------------------------------

#include <stdio.h>
#include <ftw.h>


int fn(const char *file, const struct stat *sb, int flag){

        printf("-->\n");
}


int main(int argc,char **argv){


        ftw("/etc/", fn, 5);

        return 0;
}

------------------------------------------------------

bash# gcc test.c
bash# ./a.out
-->
bash#

------------------------------------------------------

Does anyone knows what might be the problem.

tnx in advance.
