NAME
       crypto_blkcipher_get_iv - obtain IV from cipher

SYNOPSIS
       void crypto_blkcipher_get_iv(struct crypto_blkcipher * tfm, u8 * dst, unsigned int len);

ARGUMENTS
       tfm
           cipher handle

       dst
           buffer filled with the IV

       len
           length of the buffer dst

DESCRIPTION
       The caller can obtain the IV set for the block cipher referenced by the cipher handle and
       store it into the user-provided buffer. If the buffer has an insufficient space, the IV is
       truncated to fit the buffer.
