26 CURLINFO_SSL_ENGINES \- get an slist of OpenSSL crypto-engines
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_ENGINES,
31 struct curl_slist **engine_list);
33 Pass the address of a 'struct curl_slist *' to receive a linked-list of
34 OpenSSL crypto-engines supported. Note that engines are normally implemented
35 in separate dynamic libraries. Hence not all the returned engines may be
36 available at run-time. \fBNOTE:\fP you must call \fIcurl_slist_free_all(3)\fP
37 on the list pointer once you're done with it, as libcurl will not free the
43 CURL *curl = curl_easy_init();
46 struct curl_slist *engines;
47 res = curl_easy_getinfo(curl, CURLINFO_SSL_ENGINES, &engines);
48 if((res == CURLE_OK) && engines) {
49 /* we have a list, free it when done using it */
50 curl_slist_free_all(engines);
53 curl_easy_cleanup(curl);
57 Added in 7.12.3. Available in OpenSSL builds with "engine" support.
59 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
