CURLOPT_CAPATH(3) curl_easy_setopt options CURLOPT_CAPATH(3)
NAME
CURLOPT_CAPATH - specify 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 zero 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 combi-
nation 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
NULL
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
TODO
AVAILABILITY
This option is supported by the OpenSSL, GnuTLS and PolarSSL 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
