=head1 NAME
RAND_cleanup - erase the PRNG state
=head1 SYNOPSIS
#include <openssl/rand.h>
Refactor the computation of API version limits Previously, the API version limit was indicated with a numeric version number. This was "natural" in the pre-3.0.0 because the version was this simple number. With 3.0.0, the version is divided into three separate numbers, and it's only the major number that counts, but we still need to be able to support pre-3.0.0 version limits. Therefore, we allow OPENSSL_API_COMPAT to be defined with a pre-3.0.0 style numeric version number or with a simple major number, i.e. can be defined like this for any application: -D OPENSSL_API_COMPAT=0x10100000L -D OPENSSL_API_COMPAT=3 Since the pre-3.0.0 numerical version numbers are high, it's easy to distinguish between a simple major number and a pre-3.0.0 numerical version number and to thereby support both forms at the same time. Internally, we define the following macros depending on the value of OPENSSL_API_COMPAT: OPENSSL_API_0_9_8 OPENSSL_API_1_0_0 OPENSSL_API_1_1_0 OPENSSL_API_3 They indicate that functions marked for deprecation in the corresponding major release shall not be built if defined.

Prior to OpenSSL 1.1.0, RAND_cleanup() released all resources used by
the PRNG. As of version 1.1.0, it does nothing and should not be called,
