- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

# 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%
|
|
|
|
# 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);
|
|
}
|
|
}
|
|
~~~
|
|
|
|
# %AVAILABILITY%
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
