CURLINFO_SSL_ENGINES(3) | curl_easy_getinfo options | 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 implemented in separate dynamic libraries. Hence not all the returned engines may be available at run-time. NOTE: you must call curl_slist_free_all(3) on the list pointer once you're done with it, as libcurl will not free the 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.
