23 .TH CURLOPT_CAPATH 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
25 CURLOPT_CAPATH \- specify directory holding CA certificates
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
31 Pass a char * to a zero terminated string naming a directory holding multiple
32 CA certificates to verify the peer with. If libcurl is built against OpenSSL,
33 the certificate directory must be prepared using the openssl c_rehash utility.
34 This makes sense only when used in combination with the
35 \fICURLOPT_SSL_VERIFYPEER(3)\fP option.
37 The \fICURLOPT_CAPATH(3)\fP function apparently does not work in Windows due
38 to some limitation in openssl.
42 All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc.
46 This option is supported by the OpenSSL, GnuTLS and PolarSSL backends. The NSS
47 backend provides the option only for backward compatibility.
49 Returns CURLE_OK if TLS enabled, and CURLE_UNKNOWN_OPTION if not, or
50 CURLE_OUT_OF_MEMORY if there was insufficient heap space.
