bn_set_word(3) [redhat man page]

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 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. 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. 0.9.7a 2002-07-18 BN_zero(3)
