BN_set_bit(3)			    OpenSSL			 BN_set_bit(3)

NAME
       BN_set_bit, BN_clear_bit, BN_is_bit_set, BN_mask_bits, BN_lshift,
       BN_lshift1, BN_rshift, BN_rshift1 - bit operations on BIGNUMs

SYNOPSIS
	#include <openssl/bn.h>

	int BN_set_bit(BIGNUM *a, int n);
	int BN_clear_bit(BIGNUM *a, int n);

	int BN_is_bit_set(const BIGNUM *a, int n);

	int BN_mask_bits(BIGNUM *a, int n);

	int BN_lshift(BIGNUM *r, const BIGNUM *a, int n);
	int BN_lshift1(BIGNUM *r, BIGNUM *a);

	int BN_rshift(BIGNUM *r, BIGNUM *a, int n);
	int BN_rshift1(BIGNUM *r, BIGNUM *a);

DESCRIPTION
       BN_set_bit() sets bit n in a to 1 (a⎪=(1<<n)). The number is expanded
       if necessary.

       BN_clear_bit() sets bit n in a to 0 (a&=~(1<<n)). An error occurs if a
       is shorter than n bits.

       BN_is_bit_set() tests if bit n in a is set.

       BN_mask_bits() truncates a to an n bit number (a&=~((~0)>>n)).  An
       error occurs if a already is shorter than n bits.

       BN_lshift() shifts a left by n bits and places the result in r
       (r=a*2^n). BN_lshift1() shifts a left by one and places the result in r
       (r=2*a).

       BN_rshift() shifts a right by n bits and places the result in r
       (r=a/2^n). BN_rshift1() shifts a right by one and places the result in
       r (r=a/2).

       For the shift functions, r and a may be the same variable.

RETURN VALUES
       BN_is_bit_set() returns 1 if the bit is set, 0 otherwise.

       All other functions return 1 for success, 0 on error. The error codes
       can be obtained by ERR_get_error(3).

HISTORY
       BN_set_bit(), BN_clear_bit(), BN_is_bit_set(), BN_mask_bits(),
       BN_lshift(), BN_lshift1(), BN_rshift(), and BN_rshift1() are available
       in all versions of SSLeay and OpenSSL.
