NAME

       CURLOPT_CAPATH - directory holding CA certificates

SYNOPSIS

       #include <curl/curl.h>

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

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 CURLOPT_SSL_VERIFYPEER(3) option.

       The CURLOPT_CAPATH(3) 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.

DEFAULT

       A default path detected at build time.

PROTOCOLS

       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

       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);
       }

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.

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
