+## Compare Values
+
+```C
+#include <cx/json.h>
+
+int cxJsonCompare(const CxJsonValue *value,
+        const CxJsonValue *other);
+```
+
+The function `cxJsonCompare()` performs a deep comparison of two JSON values.
+It returns zero if both values are equal except for the order of object members.
+When the values are not equal, the return-value is an unspecified non-zero value.
