+# NAME
+
+CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines
+
+# SYNOPSIS
+
+~~~c
+#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 runtime. **NOTE:** you must call curl_slist_free_all(3)
+on the list pointer once you are done with it, as libcurl does not free this
+data for you.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    struct curl_slist *engines;
+    res = curl_easy_getinfo(curl, CURLINFO_SSL_ENGINES, &engines);
+    if((res == CURLE_OK) && engines) {
+      /* we have a list, free it when done using it */
+      curl_slist_free_all(engines);
+    }
+
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_getinfo(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
