# NAME
|
||
|
|
|
||
|
|
CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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 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
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
int main(void)
|
||
|
|
{
|
||
|
|
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);
|
||
|

}
