+PR_FindSymbol
+=============
+
+``PR_FindSymbol()`` will return an untyped reference to a symbol in a
+particular library given the identity of the library and a textual
+representation of the symbol in question.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prlink.h>
+
+   void* PR_FindSymbol (
+      PRLibrary *lib,
+      const char *name);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+``lib``
+   A valid reference to a loaded library, as returned by
+   :ref:`PR_LoadLibrary`, or ``NULL``.
+``name``
+   A textual representation of the symbol to resolve.
+
+
+Returns
+~~~~~~~
+
+An untyped pointer.
+
+
+Description
+-----------
+
+This function finds and returns an untyped reference to the specified
+symbol in the specified library. If the lib parameter is ``NULL``, all
+libraries known to the runtime and the main program are searched in an
+unspecified order.
+
+Use this function to look up functions or data symbols in a shared
+library. Getting a pointer to a symbol in a library does indicate that
+the library is available when the search was made. The runtime does
+nothing to ensure the continued validity of the symbol. If the library
+is unloaded, for instance, the results of any :ref:`PR_FindSymbol` calls
+become invalid as well.
