+PR_SetLibraryPath
+=================
+
+Registers a default library pathname with a runtime.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prlink.h>
+
+   PRStatus PR_SetLibraryPath(const char *path);
+
+
+Parameters
+~~~~~~~~~~
+
+The function has this parameter:
+
+``path``
+   A pointer to a character array that contains the directory path that
+   the application should use as a default. The syntax of the pathname
+   is not defined, nor whether that pathname should be absolute or
+   relative.
+
+
+Returns
+~~~~~~~
+
+The function returns one of the following values:
+
+-  If successful, ``PR_SUCCESS``.
+-  If unsuccessful, ``PR_FAILURE``. This may indicate that the function
+   cannot allocate sufficient storage to make a copy of the path string
+
+
+Description
+-----------
+
+This function registers a default library pathname with the runtime.
+This allows an environment to express policy decisions globally and
+lazily, rather than hardcoding and distributing the decisions throughout
+the code.
