These are hidden structures. They are defined in the internal include file ec_lcl.h, which present in the OpenSSL sources, but not included in the compiled distribution. Idea is that members of these structures are accessable only from within libcrypto library. Users or the library shouldn't look inside these structures, they only should operate via APIs, declared in the ec.h API could be incomplete. When dealing with other newer parts of OpenSSL API (especially EVP_PKEY_CTX API) I've encountered situations where neccessary API calls are missing. In this case best approach is to design new API function which provides neccessary functionality and sumbit a patch. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
