int BN_num_bytes(
const BIGNUM *a ); int BN_num_bits(
const BIGNUM *a ); int BN_num_bits_word(
BN_ULONG w );
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.
The size.
The BN_num_bytes(), BN_num_bits(), and BN_num_bits_word()
are available in all versions of SSLeay and OpenSSL.
