Problem1 in the discussion on global variables in threads, Ask an Expert

Engineering

Problem

1. In the discussion on global variables in threads, we used a procedure create global to allocate storage for a pointer to the variable, rather than the variable itself. Is this essential, or could the procedures work with the values themselves just as well?

2. Consider a system in which threads are implemented entirely in user space, with the runtime system getting a clock interrupt once a second. Suppose that a clock interrupt occurs while some thread is executing in the runtime system. What problem might occur? Can you suggest a way to solve it?
