CURLINFO_SSL_ENGINES(3) libcurl CURLINFO_SSL_ENGINES(3)
NAME
CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines
SYNOPSIS
#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 imple-
mented 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
All TLS based ones.
EXAMPLE
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
Added in 7.12.3. Available in OpenSSL builds with "engine" support.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
