WebThe worker thread should therefore contrive not to alter the contents of *userdata once it posts the callback, since the worker thread does not know when the main() thread will consume that data. It is often useful that userdata point to a struct, one member of which the main() thread can modify to indicate that it has consumed the data, thereby allowing the … WebInter-Process Communication (IPC) is a set of techniques for the exchange of data among two or more threads in one or more processes.
