.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
TODO
.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.
.SH "SEE ALSO"
.BR curl_easy_getinfo "(3), " curl_easy_setopt "(3), "
