NAME

       CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_ENGINES,
                                  struct curl_slist **engine_list);

DESCRIPTION

       Pass  the  address  of a 'struct curl_slist *' to receive a linked-list of OpenSSL crypto-
       engines supported.  Note  that  engines  are  normally  implemented  in  separate  dynamic
       libraries. Hence not all the returned engines may be available at run-time. NOTE: you must
       call curl_slist_free_all(3) on the list pointer once you're done with it, as libcurl  will
       not free the data for you.

PROTOCOLS

       All TLS based ones.

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.12.3. Available in OpenSSL builds with "engine" support.

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
