  .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.
  
  The application does not have to keep the string around after setting this
  option.
  .SH DEFAULT
  NULL
  .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, PolarSSL 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
