+Description
+-----------
+
+The opaque structure :ref:`PRDir` represents an open directory in the file
+system. The function :ref:`PR_OpenDir` opens a specified directory and
+returns a pointer to a :ref:`PRDir` structure, which can be passed to
+:ref:`PR_ReadDir` repeatedly to obtain successive entries (files or
+subdirectories in the open directory). To close the directory, pass the
+:ref:`PRDir` pointer to :ref:`PR_CloseDir`.
