### Set the number of threads with calling functions. ### Set the number of threads on runtime.
Examples: We provided the below functions to controll the number of threads on runtime. So far, we didn't support changing the number of threads on Windows. On Windows, these functions are dummy.
void goto_set_num_threads(int num_threads); void goto_set_num_threads(int num_threads);
