The values are 20erased before the memory is returned to the system. 21 22=head1 RETURN VALUES 23 24If the allocation fails, DH_new() returns B<NULL> and sets an error 25code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns 26a pointer to the newly allocated structure. 27 28DH_free() returns no value. 29 30=head1 SEE ALSO 31 32L<dh(3)|dh(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, 33L<DH_generate_parameters(3)|DH_generate_parameters(3)>, 34L<DH_generate_key(3)|DH_generate_key(3)> 35 36=head1 HISTORY 37 38DH_new() and DH_free() are available in all versions of SSLeay and OpenSSL. 39 40=cut 41
