CURLOPT_PROXY_CAPATH(3)             libcurl            CURLOPT_PROXY_CAPATH(3)




NAME

       CURLOPT_PROXY_CAPATH - directory holding HTTPS proxy CA certificates


SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_CAPATH, char *capath);


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
       CURLOPT_PROXY_SSL_VERIFYPEER(3) is enabled (which it is by default).

       The application does not have to keep the string around after setting
       this option.

       The default value for this can be figured out with CURLINFO_CAPATH(3).


DEFAULT

       NULL


PROTOCOLS

       Everything used over an HTTPS proxy


EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           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");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }


AVAILABILITY

       Added in 7.52.0

       This option is supported by the OpenSSL, GnuTLS, and mbedTLS (since
       7.56.0) backends.


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
