Define a new type "struct cshared". This can be used as a tool to manipulate a global counter with thread-safety ensured. Each thread would declare its thread-local cshared type, which would point to a global counter. Each thread can then add/substract value to their owned thread-local cshared instance via cshared_add(). If the difference exceed a configured limit, either positively or negatively, the global counter is updated and thread-local instance is reset to 0. Each thread can safely read the global counter value using cshared_read().
