.. code::
#include <prlink.h>
char* PR_GetLibraryPath(void);
Parameters

A copy of the default library pathname string. In case of error, returns

Description
-----------
This function retrieves the current default library pathname, copies it,
and returns the copy. If sufficient storage cannot be allocated to
contain the copy, the function returns ``NULL``. Storage for the result
is allocated by the runtime and becomes the responsibility of the
caller. When it is no longer used, free it using :ref:`PR_FreeLibraryName`.
