 If the function fails the return value is @code{NULL}.

+The four functions described so far in this section all work on a state
+which is shared by all threads.  The state is not directly accessible to
+the user and can only be modified by these functions.  This makes it
+hard to deal with situations where each thread should have its own
+pseudo-random number generator.
+
+The GNU C library contains four additional functions which contain the
+state as an explicit parameter and therefore make it possible to handle
+thread-local PRNGs.  Beside this there are no difference.  In fact, the
+four functions already discussed are implemented internally using the
+following interfaces.
+
+The @file{stdlib.h} header contains a definition of the following type:
+
+@comment stdlib.h
+@comment GNU
+@deftp {Data Type} {struct random_data}
+
+Objects of type @code{struct random_data} contain the information
+necessary to represent the state of the PRNG.  Although a complete
+definition of the type is present the type should be treated as opaque.
+@end deftp
+
+The functions modifying the state follow exactly the already described
+functions.
+
+@comment stdlib.h
+@comment GNU
+@deftypefun int random_r (struct random_data *restrict @var{buf}, int32_t *restrict @var{result})
+The @code{random_r} function behaves exactly like the @code{random}
+function except that it uses and modifies the state in the object
+pointed to by the first parameter instead of the global state.
