+PR_OpenDir
+==========
+
+Opens the directory with the specified pathname.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prio.h>
+
+   PRDir* PR_OpenDir(const char *name);
+
+
+Parameter
+~~~~~~~~~
+
+The function has the following parameter:
+
+``name``
+   The pathname of the directory to be opened.
+
+
+Returns
+~~~~~~~
+
+-  If the directory is successfully opened, a :ref:`PRDir` object is
+   dynamically allocated and the function returns a pointer to it.
+-  If the directory cannot be opened, the function returns ``NULL``.
+
+
+Description
+-----------
+
+:ref:`PR_OpenDir` opens the directory specified by the pathname ``name``
+and returns a pointer to a directory stream (a :ref:`PRDir` object) that
+can be passed to subsequent :ref:`PR_ReadDir` calls to get the directory
+entries (files and subdirectories) in the directory. The :ref:`PRDir`
+pointer should eventually be closed by a call to :ref:`PR_CloseDir`.
