CURLOPT_PROXY_CAPATH(3) | curl_easy_setopt options | CURLOPT_PROXY_CAPATH(3) |
NAME¶
CURLOPT_PROXY_CAPATH - specify directory holding 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.
DEFAULT¶
NULL
PROTOCOLS¶
Everything used over an HTTPS proxy
EXAMPLE¶
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); }
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.
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
