int
BN_cmp(BIGNUM
*a, BIGNUM *b);
int
BN_ucmp(BIGNUM
*a, BIGNUM *b);
int
BN_is_zero(BIGNUM
*a);

DESCRIPTION
BN_cmp() compares the numbers
a and b.
BN_ucmp() compares their absolute values.
BN_is_zero(),
BN_is_one() and
BN_is_word() test if
a equals 0, 1, or
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.
RETURN VALUES
BN_cmp() returns -1 if
a<b, 0 if
a==b, and 1
if a>b.
BN_ucmp() is the same using the absolute
values of a and
b.
BN_is_zero(),
BN_is_one(),
BN_is_word(), and
BN_is_odd() return 1 if the condition is
true, 0 otherwise.
