CURLINFO_S...ERIFYRESULT(3) Library Functions Manual CURLINFO_S...ERIFYRESULT(3) NAME CURLINFO_SSL_VERIFYRESULT - result of the certificate verification SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_VERIFYRESULT, long *result); DESCRIPTION Pass a pointer to a long to receive the result of the server SSL certifi- cate verification that was requested (using the CURLOPT_SSL_VERIFYPEER(3) option). 0 is a positive result. Non-zero is an error. PROTOCOLS This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. This option works only with the following TLS backends: GnuTLS and OpenSSL EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode result; long verifyresult; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); result = curl_easy_perform(curl); if(result != CURLE_OK) { printf("error: %s\n", curl_easy_strerror(result)); curl_easy_cleanup(curl); return 1; } result = curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT, &verifyresult); if(result == CURLE_OK) { printf("The peer verification said %s\n", (verifyresult ? "bad" : "fine")); } curl_easy_cleanup(curl); } } AVAILABILITY Added in curl 7.5 RETURN VALUE curl_easy_getinfo(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
