The -number is expanded if necessary. - -BN_clear_bit() sets bit B<n> in B<a> to 0 (C<a&=~(1E<lt>E<lt>n)>). An -error occurs if B<a> is shorter than B<n> bits. - -BN_is_bit_set() tests if bit B<n> in B<a> is set. - -BN_mask_bits() truncates B<a> to an B<n> bit number -(C<a&=~((~0)E<gt>E<gt>n)>). An error occurs if B<a> already is -shorter than B<n> bits. - -BN_lshift() shifts B<a> left by B<n> bits and places the result in -B<r> (C<r=a*2^n>). BN_lshift1() shifts B<a> left by one and places -the result in B<r> (C<r=2*a>). - -BN_rshift() shifts B<a> right by B<n> bits and places the result in -B<r> (C<r=a/2^n>). BN_rshift1() shifts B<a> right by one and places -the result in B<r> (C<r=a/2>). - -For the shift functions, B<r> and B<a> may be the same variable. - -=head1 RETURN VALUES - -BN_is_bit_set() returns 1 if the bit is set, 0 otherwise. - -All other functions return 1 for success, 0 on error. The error codes -can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. - -=head1 SEE ALSO - -L<bn(3)|bn(3)>, L<BN_num_bytes(3)|BN_num_bytes(3)>, L<BN_add(3)|BN_add(3)> - -=head1 HISTORY - -BN_set_bit(), BN_clear_bit(), BN_is_bit_set(), BN_mask_bits(), -BN_lshift(), BN_lshift1(), BN_rshift(), and BN_rshift1() are available -in all versions of SSLeay and OpenSSL. - -=cut |
