A few things:

First, you're talking on the curl-users list and not the curl-library list
where most development and developers are hanging out so this email doesn't
really reach the best target here.

We of course appreciate a patch! Can you submit it as a pull-request over on
github ( so that we can get it through all
the automated tests and verifications?

On the patch itself:

- "CURLOPT_CURVES" might be a little too brief name

- there's no docs

- It seems SSL_CTX_set1_curves_list() was added in OpenSSL 1.0.2 and we're
   still supporting older OpenSSL versions so we need some configure checks
   and #ifdef dance added...
