RAND_cleanup - erase the PRNG state
#include <openssl/rand.h>
#if OPENSSL_API_COMPAT < 0x10100000L
void RAND_cleanup(void)
#endif
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, since no
explicit initialisation or de-initialisation is necessary. See
OPENSSL_init_crypto(3).
RAND_cleanup() returns no value.
RAND_cleanup() was deprecated in OpenSSL 1.1.0; do not use it. See
OPENSSL_init_crypto(3)
