BN_ZERO(3)		     OpenSSL		       BN_ZERO(3)

NAME
     BN_zero, BN_one, BN_value_one, BN_set_word, BN_get_word -
     BIGNUM assignment operations

SYNOPSIS
      #include <openssl/bn.h>

      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);

DESCRIPTION
     BN_zero(), BN_one() and BN_set_word() set a to the values 0,
     1 and w respectively.  BN_zero() and BN_one() are macros.

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

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

RETURN VALUES
     BN_get_word() returns the value a, and 0xffffffffL if a can-
     not 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.

BUGS
     Someone might change the constant.

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

SEE ALSO
     bn(3), BN_bn2bin(3)

HISTORY
     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.
