=head1 NAME
-RAND_add, RAND_seed, RAND_status - add
+RAND_add, RAND_seed, RAND_status, RAND_event, RAND_screen - add
entropy to the PRNG
=head1 SYNOPSIS
int RAND_status(void);
+ #if OPENSSL_API_COMPAT < 0x10100000L
+ int RAND_event(UINT iMsg, WPARAM wParam, LPARAM lParam);
+ void RAND_screen(void);
+ #endif
+
=head1 DESCRIPTION
RAND_add() mixes the B<num> bytes at B<buf> into the PRNG state. Thus,
RAND_seed() is equivalent to RAND_add() when B<num == entropy>.
+RAND_event() and RAND_screen() are deprecated and should not be called.
+
=head1 RETURN VALUES
RAND_status() returns 1 if the PRNG has been seeded
with enough data, 0 otherwise.
+RAND_event() calls RAND_poll() and returns RAND_status().
+
+RAND_screen calls RAND_poll().
+
The other functions do not return values.
+=head1 HISTORY
+
+RAND_event() and RAND_screen() are deprecated since OpenSSL
+1.1.0. Use the functions described above instead.
