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
