+.TH CURLINFO_SSL_ENGINES 3 "1 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
+.SH NAME
+CURLINFO_SSL_ENGINES \- get an slist of OpenSSL crypto-engines
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_ENGINES,
+                           struct curl_slist **engine_list);
+.SH 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. \fBNOTE:\fP you must call \fIcurl_slist_free_all(3)\fP
+on the list pointer once you're done with it, as libcurl will not free the
+data for you.
+.SH PROTOCOLS
+All TLS based ones.
+.SH EXAMPLE
+.nf
+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);
+}
+.fi
+.SH AVAILABILITY
+Added in 7.12.3. Available in OpenSSL builds with "engine" support.
+.SH RETURN VALUE
+Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
