|  | =head1 NAME | 
|  |  | 
|  | RAND_cleanup - erase the PRNG state | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/rand.h> | 
|  |  | 
|  | The following function has been deprecated since OpenSSL 1.1.0, and can be | 
|  | hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, | 
|  | see L<openssl_user_macros(7)>: | 
|  |  | 
|  | void RAND_cleanup(void); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | 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 | 
|  | 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. |
