This option has no effect unless set after \fICURLOPT_SSLENGINE(3)\fP. .SH DEFAULT None .SH PROTOCOLS All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); curl_easy_setopt(curl, CURLOPT_SSLENGINE, "dynamic"); curl_easy_setopt(curl, CURLOPT_SSLENGINE_DEFAULT, 1L); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } .fi .SH AVAILABILITY Only if the SSL backend is OpenSSL built with engine support. .SH RETURN VALUE CURLE_OK - Engine set as default. CURLE_SSL_ENGINE_SETFAILED - Engine could not be set as default. CURLE_NOT_BUILT_IN - Option not built in, OpenSSL is not the SSL backend. CURLE_UNKNOWN_OPTION - Option not recognized.
