BNcmp(3) OpenSSL BNcmp(3)

NAME
       BNcmp, BNucmp, BNiszero, BNisone, BNisword, BNisodd - BIGNUM
       comparison and test functions

SYNOPSIS
        #include 

        int BNcmp(BIGNUM *a, BIGNUM *b);
        int BNucmp(BIGNUM *a, BIGNUM *b);

        int BNiszero(BIGNUM *a);
        int BNisone(BIGNUM *a);
        int BNisword(BIGNUM *a, BNULONG w);
        int BNisodd(BIGNUM *a);

DESCRIPTION
       BNcmp() compares the numbers aa and bb. BNucmp() compares their
       absolute values.

       BNiszero(), BNisone() and BNisword() test if aa equals 0, 1, or ww
       respectively. BNisodd() tests if a is odd.

       BNiszero(), BNisone(), BNisword() and BNisodd() are macros.

RETURN VALUES
       BNcmp() returns -1 if aa < bb, 0 if aa == bb and 1 if aa > bb. BNucmp() is
       the same using the absolute values of aa and bb.

       BNiszero(), BNisone() BNisword() and BNisodd() return 1 if the
       condition is true, 0 otherwise.

HISTORY       BNcmp(), BNucmp(), BNiszero(), BNisone() and BNisword() are
       available in all versions of SSLeay and OpenSSL.  BNisodd() was added
       in SSLeay 0.8.
