| .TH CURLOPT_PROXY_CAPATH 3 "November 04, 2020" "libcurl 7.78.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_PROXY_CAPATH \- specify directory holding proxy CA certificates |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath); |
| .SH DESCRIPTION |
| Pass a char * to a null-terminated string naming a directory holding multiple |
| CA certificates to verify the HTTPS proxy with. If libcurl is built against |
| OpenSSL, the certificate directory must be prepared using the openssl c_rehash |
| utility. This makes sense only when \fICURLOPT_PROXY_SSL_VERIFYPEER(3)\fP is |
| enabled (which it is by default). |
| |
| The application does not have to keep the string around after setting this |
| option. |
| .SH DEFAULT |
| NULL |
| .SH PROTOCOLS |
| Everything used over an HTTPS proxy |
| .SH EXAMPLE |
| .nf |
| CURL *curl = curl_easy_init(); |
| if(curl) { |
| curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); |
| /* using an HTTPS proxy */ |
| curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:443"); |
| curl_easy_setopt(curl, CURLOPT_PROXY_CAPATH, "/etc/cert-dir"); |
| ret = curl_easy_perform(curl); |
| curl_easy_cleanup(curl); |
| } |
| .fi |
| .SH AVAILABILITY |
| Added in 7.52.0 |
| |
| 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 |
