RAND_cleanup - erase the PRNG state

=head1 SYNOPSIS

 #include <openssl/rand.h>

the PRNG.  As of version 1.1.0, it does nothing and should not be called,
since no explicit initialisation or de-initialisation is necessary. See
L<OPENSSL_init_crypto(3)>.

=head1 RETURN VALUES

RAND_cleanup() returns no value.

=head1 HISTORY

RAND_cleanup() was deprecated in OpenSSL 1.1.0; do not use it.
