+=head1 NAME
+
+BN_zero, BN_one, BN_value_one, BN_set_word, BN_get_word - BIGNUM assignment
+operations
+
+=head1 SYNOPSIS
+
+ #include <openssl/bn.h>
+
+ void BN_zero(BIGNUM *a);
+ int BN_one(BIGNUM *a);
+
+ const BIGNUM *BN_value_one(void);
+
+ int BN_set_word(BIGNUM *a, BN_ULONG w);
+ BN_ULONG BN_get_word(BIGNUM *a);
+
+Deprecated:
+
+ #if OPENSSL_API_COMPAT < 0x00908000L
+ int BN_zero(BIGNUM *a);
+ #endif
+
+=head1 DESCRIPTION
+
+B<BN_ULONG> is a macro that will be an unsigned integral type optimied
+for the most efficient implementation on the local platform.
+
+BN_zero(), BN_one() and BN_set_word() set B<a> to the values 0, 1 and
+B<w> respectively.  BN_zero() and BN_one() are macros.
+
+BN_value_one() returns a B<BIGNUM> constant of value 1. This constant
+is useful for use in comparisons and assignment.
+
+BN_get_word() returns B<a>, if it can be represented as a B<BN_ULONG>.
+
+=head1 RETURN VALUES
+
+BN_get_word() returns the value B<a>, or all-bits-set if B<a> cannot
+be represented as a B<BN_ULONG>.
+
+BN_one(), BN_set_word() and the deprecated version of BN_zero()
+return 1 on success, 0 otherwise.
+BN_value_one() returns the constant.
+The preferred version of BN_zero() never fails and returns no value.
+
+=head1 BUGS
+
+If a B<BIGNUM> is equal to the value of all-bits-set, it will collide
+with the error condition returned by BN_get_word() which uses that
+as an error value.
+
+B<BN_ULONG> should probably be a typedef.
