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 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 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.
