+## Clone Values
+
+```C
+#include <cx/json.h>
+
+CxJsonValue* cxJsonClone(const CxJsonValue* value,
+        const CxAllocator* allocator);
+
+CxJsonValue* cxJsonCloneFunc(
+        CxJsonValue* target, const CxJsonValue* source,
+        const CxAllocator* allocator, void *data);
+```
+
+The function `cxJsonClone()` creates a deep clone of the specified value using the specified allocator.
+The function `cxJsonCloneFunc()` is a `cx_clone_func` compatible version of the same function
+(the `data` argument is unused).
