=head1 NAME
|
|
|
|
BN_cmp, BN_ucmp, BN_is_zero, BN_is_one, BN_is_word, BN_is_odd - BIGNUM comparison and test functions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/bn.h>
|
|
|
|
int BN_cmp(BIGNUM *a, BIGNUM *b);
|
|
int BN_ucmp(BIGNUM *a, BIGNUM *b);
|
|
|
|
int BN_is_zero(BIGNUM *a);
|
|
int BN_is_one(BIGNUM *a);
|
|
int BN_is_word(BIGNUM *a, BN_ULONG w);
|
|
int BN_is_odd(BIGNUM *a);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
BN_cmp() compares the numbers B<a> and B<b>. BN_ucmp() compares their
|
|
absolute values.
|
|
|
|
BN_is_zero(), BN_is_one() and BN_is_word() test if B<a> equals 0, 1,
|
|
or B<w> respectively. BN_is_odd() tests if a is odd.
|
|
|
|
BN_is_zero(), BN_is_one(), BN_is_word() and BN_is_odd() are macros.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
BN_cmp() returns -1 if B<a> E<lt> B<b>, 0 if B<a> == B<b> and 1 if
|
|
B<a> E<gt> B<b>. BN_ucmp() is the same using the absolute values
|
|
of B<a> and B<b>.
|
|
|
|
BN_is_zero(), BN_is_one() BN_is_word() and BN_is_odd() return 1 if
|
|
the condition is true, 0 otherwise.
