5 BN_cmp, BN_ucmp, BN_is_zero, BN_is_one, BN_is_word, BN_is_odd - BIGNUM comparison and test functions
9 #include <openssl/bn.h>
11 int BN_cmp(BIGNUM *a, BIGNUM *b);
12 int BN_ucmp(BIGNUM *a, BIGNUM *b);
14 int BN_is_zero(BIGNUM *a);
15 int BN_is_one(BIGNUM *a);
16 int BN_is_word(BIGNUM *a, BN_ULONG w);
17 int BN_is_odd(BIGNUM *a);
21 BN_cmp() compares the numbers B<a> and B<b>. BN_ucmp() compares their
24 BN_is_zero(), BN_is_one() and BN_is_word() test if B<a> equals 0, 1,
25 or B<w> respectively. BN_is_odd() tests if a is odd.
27 BN_is_zero(), BN_is_one(), BN_is_word() and BN_is_odd() are macros.
31 BN_cmp() returns -1 if B<a> E<lt> B<b>, 0 if B<a> == B<b> and 1 if
32 B<a> E<gt> B<b>. BN_ucmp() is the same using the absolute values
35 BN_is_zero(), BN_is_one() BN_is_word() and BN_is_odd() return 1 if
36 the condition is true, 0 otherwise.
