.TH CURLOPT_CAPATH 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_CAPATH \- specify directory holding CA certificates
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
.SH 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 combination with the
\fICURLOPT_SSL_VERIFYPEER(3)\fP option.

The \fICURLOPT_CAPATH(3)\fP function apparently does not work in Windows due
to some limitation in openssl.
.SH DEFAULT
NULL
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
TODO
.SH AVAILABILITY
This option is supported by the OpenSSL, GnuTLS and PolarSSL backends. The NSS
backend provides the option only for backward compatibility.
.SH RETURN VALUE
Returns CURLE_OK if TLS enabled, and CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
