Accessing Directories
=====================

   The facilities described in this section let you read the contents
of a directory file.  This is useful if you want your program to list
all the files in a directory, perhaps as part of a menu.

   The `opendir' function opens a "directory stream" whose elements are
directory entries.  You use the `readdir' function on the directory
stream to retrieve these entries, represented as `struct dirent'
objects.  The name of the file for each entry is stored in the `d_name'
member of this structure.  There are obvious parallels here to the
stream facilities for ordinary files, described in Note: I/O on
Streams.
