EC_GROUP_have_precompute_mult tests whether precomputation has already been done. See <a href="../man3/EC_GROUP_copy.html">EC_GROUP_copy(3)</a> for information about the generator. Precomputation functionality was deprecated in OpenSSL 3.0. Users of EC_GROUP_precompute_mult() and EC_GROUP_have_precompute_mult() should switch to named curves which OpenSSL has hardcoded lookup tables for.</p>
