| .TH CURLOPT_CAPATH 3 "May 14, 2021" "libcurl 7.78.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_CAPATH \- specify directory holding CA certificates |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath); |
| .SH DESCRIPTION |
| Pass a char * to a null-terminated string naming a directory holding multiple |
| CA certificates to verify the peer with. If libcurl is built against OpenSSL, |
| the certificate directory must be prepared using the openssl c_rehash utility. |
| This makes sense only when used in combination with the |
| \fICURLOPT_SSL_VERIFYPEER(3)\fP option. |
| |
| The \fICURLOPT_CAPATH(3)\fP function apparently does not work in Windows due |
| to some limitation in openssl. |
| |
| The application does not have to keep the string around after setting this |
| option. |
| .SH DEFAULT |
| A default path detected at build time. |
| .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_CAPATH, "/etc/cert-dir"); |
| ret = curl_easy_perform(curl); |
| curl_easy_cleanup(curl); |
| } |
| .fi |
| .SH AVAILABILITY |
| This option is supported by the OpenSSL, GnuTLS and mbedTLS (since 7.56.0) |
| backends. The NSS backend provides the option only for backward compatibility. |
| .SH RETURN VALUE |
| CURLE_OK if supported; or an error such as: |
| |
| CURLE_NOT_BUILT_IN - Not supported by the SSL backend |
| |
| CURLE_UNKNOWN_OPTION |
| |
| CURLE_OUT_OF_MEMORY |
