 Hi  i am working on #4674
     currently I'm not able to get it to produce the error
     my code looks like this
     Tested in on IMFS
    {{{
   #ifdef HAVE_CONFIG_H
     #include "config.h"
     #endif

     #include <dirent.h>
     #include <stdio.h>
     #include <sys/types.h>
     #include <fcntl.h>
     #include <dirent.h>
     #include <string.h>
     #include <unistd.h>
     #include <errno.h>
     #include <rtems/imfs.h>

     const char rtems_test_name[] = "FSREADDIR ";
     int test( void );

     int test( void )
     {
        char *many_files[] = {"a", "b","c"};


       printf( "\nchdir to the root directory\n" );
      int  status = chdir( "/" );
       printf( "chdir() status : %d\n\n", status );
     for (int i = 0; i<3; i++) {
         printf("Create %s\n", many_files[i]);
         int fd = open (many_files[i], O_CREAT, S_IRWXU);
         close (fd);
       }
         struct dirent* direntp;
          DIR* dirp;
         dirp = opendir( "/" );
         if( dirp != NULL ) {
             for(;;) {
                 direntp = readdir( dirp );
                 if( direntp == NULL ) break;

                 printf( "%s\n", direntp->d_name );
             }

             closedir( dirp );

         }

        status =  unlink("/b");
         printf( "removing the second directory  : %d\n\n", status );
        dirp = opendir( "/" );
         if( dirp != NULL ) {
             for(;;) {
                 direntp = readdir( dirp );
                 if( direntp == NULL ) break;

                 printf( "%s\n", direntp->d_name );
             }

             closedir( dirp );

         }

        return 0;

     }
  }}}


     Am i unlinking it correctly?
