OpenSSL renamed function SSLeay to OpenSSL_version_num.

So, so depending on what version of library we work with we

need to call either SSLeay or OpenSSL_version_num.

What is the best way to do it?

The following is one approach:

(or (ignore-errors

(cffi:foreign-funcall "OpenSSL_version_num" :long))

(ignore-errors

(cffi:foreign-funcall "SSLeay" :long)))

but it won't work on Corman Lisp because it doesn't

support cffi:foreign-funcall.

I would like to be fully portable. Is there a better way?

Best regards,
