NAME
       BN_num_bits, BN_num_bytes, BN_num_bits_word - get BIGNUM size

SYNOPSIS
        #include <openssl/bn.h>

        int BN_num_bytes(const BIGNUM *a);

        int BN_num_bits(const BIGNUM *a);

        int BN_num_bits_word(BN_ULONG w);

DESCRIPTION
       These functions return the size of a BIGNUM in bytes or bits, and the
       size of an unsigned integer in bits.

       BN_num_bytes() is a macro.

RETURN VALUES
       The size.
