I know what you mean, but I just don't know why you want to emulate that in C. There is a real problem of people writing APIs that don't let you pass in data with your function pointer - the thread local method can solve 99% of those without changes to the original API. But if you really want to do all kinds of first class functions with data, do you want to use C? |
