halide_task_t

int(*) halide_task_t (void *user_context, int task_number, uint8_t *closure)

Define halide_do_par_for to replace the default thread pool implementation.

halide_shutdown_thread_pool can also be called to release resources used by the default thread pool on platforms where it makes sense. See Func::set_custom_do_task and Func::set_custom_do_par_for. Should return zero if all the jobs return zero, or an arbitrarily chosen return value from one of the jobs otherwise.
