=head1 NAME
-EVP_PKEY_new, EVP_PKEY_free - private key allocation functions.
+EVP_PKEY_new, EVP_PKEY_up_ref, EVP_PKEY_free - private key allocation functions.
=head1 SYNOPSIS
#include <openssl/evp.h>
EVP_PKEY *EVP_PKEY_new(void);
+ void EVP_PKEY_up_ref(EVP_PKEY *key);
void EVP_PKEY_free(EVP_PKEY *key);
=head1 DESCRIPTION
-The EVP_PKEY_new() function allocates an empty B<EVP_PKEY>
-structure which is used by OpenSSL to store private keys.
+The EVP_PKEY_new() function allocates an empty B<EVP_PKEY> structure which is
+used by OpenSSL to store private keys. The reference count is set to B<1>.
-EVP_PKEY_free() frees up the private key B<key>.
-If B<key> is NULL, nothing is done.
+EVP_PKEY_up_ref() increments the reference count of B<key>.
+
+EVP_PKEY_free() decrements the reference count of B<key> and, if the reference
+count is zero, frees it up. If B<key> is NULL, nothing is done.
=head1 NOTES
-The B<EVP_PKEY> structure is used by various OpenSSL functions
-which require a general private key without reference to any
-particular algorithm.
+The B<EVP_PKEY> structure is used by various OpenSSL functions which require a
+general private key without reference to any particular algorithm.
-The structure returned by EVP_PKEY_new() is empty. To add a
-private key to this empty structure the functions described in
-L<EVP_PKEY_set1_RSA(3)> should be used.
+The structure returned by EVP_PKEY_new() is empty. To add a private key to this

=head1 RETURN VALUES
-EVP_PKEY_new() returns either the newly allocated B<EVP_PKEY>
-structure of B<NULL> if an error occurred.
+EVP_PKEY_new() returns either the newly allocated B<EVP_PKEY> structure or
+B<NULL> if an error occurred.
-EVP_PKEY_free() does not return a value.
