int ret;

"key" is undefined. This was probably supposed to be "eckey" (which does
have a "group" member).

ECDSA_verify() verifies that the signature in sig of size siglen is a valid
ECDSA signature of the hash value value dgst of size dgstlen using the
public key eckey. The parameter type is ignored.
"value value" should be "value".
