() helps you group patterns. \(^.\) is represented by \1. Similarly \(.*\) is represented by \2
You cannot use [] instead of ()

bn_value_one
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.
