+# NAME
+
+CURLINFO_CAINFO - get the default built-in CA certificate path
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAINFO, char **path);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a char pointer to receive the pointer to a null-terminated
+string holding the default built-in path used for the CURLOPT_CAINFO(3)
+option unless set by the user.
+
+Note that in a situation where libcurl has been built to support multiple TLS
+libraries, this option might return a string even if the specific TLS library
+currently set to be used does not support CURLOPT_CAINFO(3).
+
+This is a path identifying a single file containing CA certificates.
+
+The **path** pointer is set to NULL if there is no default path.
+

+    if(cainfo) {
+      printf("default ca info path: %s\n", cainfo);
