- * Name: readdir_r
- *
- * Description:
- *   The readdir() function returns a pointer to a dirent
- *   structure representing the next directory entry in the
- *   directory stream pointed to by dir.  It returns NULL on
- *   reaching the end-of-file or if an error occurred.
- *
- * Inputs:
- *   dirp -- An instance of type DIR created by a previous
- *     call to opendir();
- *   entry -- The  storage  pointed to by entry must be large
- *     enough for a dirent with an array of char d_name
- *     members containing at least {NAME_MAX}+1 elements.
- *   result -- Upon successful return, the pointer returned
- *     at *result shall have the  same  value  as  the 
- *     argument entry. Upon reaching the end of the directory
- *     stream, this pointer shall have the value NULL.
- *
- * Return:
- *   If successful, the readdir_r() function return s zero;
- *   otherwise, an error number is returned to indicate the
- *   error.
- *
- *   EBADF   - Invalid directory stream descriptor dir
