CURLOPT_PROXY_CAPATH(3) curl_easy_setopt options 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 CUR-
LOPT_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
