.TH CURLOPT_CAPATH 3 "September 20, 2022" "libcurl 7.86.0" "curl_easy_setopt options"

.SH NAME
CURLOPT_CAPATH \- directory holding CA certificates
.SH SYNOPSIS
.nf
#include <curl/curl.h>

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

The \fICURLOPT_CAPATH(3)\fP 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.

The default value for this can be figured out with \fICURLINFO_CAPATH(3)\fP.
.SH DEFAULT
A default path detected at build time.
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
.nf
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);
}
.fi
.SH 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.
.SH 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
