Demonstrates how to setup the connection to do an opendir/readdir on a remote file system. This sample must be run against a server in the same tree as the server that you are running this on.

Sample Code

#include <stdio.h>
#include <stdlib.h>
#include <nwcalls.h>
#include <nwnet.h>
#include <errno.h>
#include <nwerrno.h>
#include <fcntl.h>
#include <nwdsapi.h> 
#include <sys/stat.h>
#include <unistd.h>
#include <string.h>
#include <nwcntask.h>
#include <nwclxcon.h>
#include <dirent.h>
#include <nwconn.h>

      goto ERR;
   } 
   printf("NWDSAuthenticate success\r\n");   

   printf("path = %s\r\n", path);

   dirEnt = opendir(path);
   if(NULL == dirEnt)
   {
      printf("Error %d\r\n", errno);
      goto ERR;
   }

   while((fileEnt = readdir(dirEnt)) != NULL)   
      {   
         
         printf("%s\r\n", fileEnt->d_name);
