+# NAME
+
+CURLOPT_CAPATH - directory holding CA certificates
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer 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
+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.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+The default value for this can be figured out with CURLINFO_CAPATH(3).
+
+# DEFAULT
+
+A path detected at build time.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    curl_easy_setopt(curl, CURLOPT_CAPATH, "/etc/cert-dir");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# 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
