Non-zero is an error. # EXAMPLE ~~~c int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; long verifyresult; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); res = curl_easy_perform(curl); if(res) { printf("error: %s\n", curl_easy_strerror(res)); curl_easy_cleanup(curl); return 1; } res = curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT, &verifyresult); if(!res) { printf("The peer verification said %s\n", (verifyresult ? "bad" : "fine")); } curl_easy_cleanup(curl); } } ~~~ # AVAILABILITY Added in 7.5. Only set by the OpenSSL/libressl/boringssl and GnuTLS backends. # RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
