Using ftw()

[CaptRage61]

Does anyone know how to use file tree walk, ftw() to list all of the files and directories and the directories files? I want to create a quick little program like the other one I was trying to write that displays everything recursivly with ftw().

What OS, what architecture, what code do you already have, etc..

OS is linux

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <dirent.h>
#include <errno.h>
#include <string.h>
#include <stdlib.h>


void search ( char *filename , char *dirname ){
  int f = 0;
  struct dirent *dirPointer;
  DIR *d;
  d = opendir( dirname );


   if ( d == NULL ) {
        fprintf( stderr, "%s %d: opendir() failed (%s)\n",
            dirname, errno, strerror( errno ));
        exit( EXIT_FAILURE );
    }
   while ( (dirPointer=readdir(d)) != NULL ) {
     if (strcmp( dirPointer->d_name, filename) == 0 ) {
         // print absolute path of file
         printf("File located\n");
         f = 1;
       }

}
if ( f == 0 ) {
printf("File not found\n");
}
closedir ( d );
printf("\n");
}

int main( int argc, char *argv[] ) {
    int x = argc;
    int count;
    printf("Number of args: %d\n",x);
     if ( x == 2 ){
      //search for file or dir in current dir
      printf("Searching\n");
      search( argv[1] , "." );
    }
     if ( x > 2 )  {
        //first n-1 are files to search for
        //n is the folder to search

        for ( count = 2 ; count < argc ; count++ ) {
            search( argv[count],argv[argc]);

}
    }
     if ( x == 1 ) {
        printf("Not enough input\n");
     }

return 0;
