.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, POP3, SMTPS etc.
.SH EXAMPLE
TODO
.SH AVAILABILITY
This option is OpenSSL-specific and does nothing if libcurl is built to use
GnuTLS. NSS-powered libcurl 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.
