BN_zero() and BN_one() are macros. + +BN_value_one() returns a B<BIGNUM> constant of value 1. This constant +is useful for use in comparisons and assignment. + +BN_get_word() returns B<a>, if it can be represented as an unsigned +long. + +=head1 RETURN VALUES + +BN_get_word() returns the value B<a>, and 0xffffffffL if B<a> cannot +be represented as an unsigned long. + +BN_one(), BN_set_word() and the deprecated version of BN_zero() +return 1 on success, 0 otherwise. +BN_value_one() returns the constant. +The preferred version of BN_zero() never fails and returns no value. + +=head1 BUGS + +Someone might change the constant. + +If a B<BIGNUM> is equal to 0xffffffffL it can be represented as an +unsigned long but this value is also returned on error. + +=head1 SEE ALSO + +L<bn(3)>, L<BN_bn2bin(3)> + +=head1 COPYRIGHT + +Copyright 2000-2016 The OpenSSL Project Authors.
