      #include 

      int BN_zero(BIGNUM *a);
      int BN_one(BIGNUM *a);

      const BIGNUM *BN_value_one(void);

      int BN_set_word(BIGNUM *a, unsigned long w);
      unsigned long BN_get_word(BIGNUM *a);


DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
     BN_zero(), BN_one() and BN_set_word() set aaaa to the values 0,
     1 and wwww respectively.  BN_zero() and BN_one() are macros.

     BN_value_one() returns a BBBBIIIIGGGGNNNNUUUUMMMM constant of value 1. This
     constant is useful for use in comparisons and assignment.

     BN_get_word() returns aaaa, if it can be represented as an
     unsigned long.

RRRREEEETTTTUUUURRRRNNNN VVVVAAAALLLLUUUUEEEESSSS
     BN_get_word() returns the value aaaa, and 0xffffffffL if aaaa
     cannot be represented as an unsigned long.

     BN_zero(), BN_one() and BN_set_word() return 1 on success, 0
     otherwise.  BN_value_one() returns the constant.

BBBBUUUUGGGGSSSS
     Someone might change the constant.

     If a BBBBIIIIGGGGNNNNUUUUMMMM is equal to 0xffffffffL it can be represented as
     an unsigned long but this value is also returned on error.

HHHHIIIISSSSTTTTOOOORRRRYYYY
     BN_zero(), BN_one() and BN_set_word() are available in all
     versions of SSLeay and OpenSSL. BN_value_one() and
     BN_get_word() were added in SSLeay 0.8.

     BN_value_one() was changed to return a true const BIGNUM *
     in OpenSSL 0.9.7.
