Use pointers to incomplete struct types. If an argument of a not suitable type is passed to a function of any string collection, C compiler will warn: warning: passing argument 1 of <func> from incompatible pointer type C++ compiler will raise an error, for example: error: cannot convert 'cef_string_list_t' ... to 'cef_string_multimap_t' With the previously used `void*` pointer types, such errors in a code were not diagnosed.
