| .TH CURLINFO_SSL_ENGINES 3 "October 31, 2021" "libcurl 7.80.0" "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 are 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. |
| .SH "SEE ALSO" |
| .BR curl_easy_getinfo "(3), " curl_easy_setopt "(3), " |
