示例1: main
int main()
{
srand(time(0));
// Custom scheduling is not required - can be integrated
// to other systems transparently
main_tasks.push([]
{
asynchronous([]
{
return async_user_handler(),
finished = true;
});
});
Task task;
while(!finished)
{
main_tasks.pop(task);
task();
}
cout << "Done" << std::endl;
return EXIT_SUCCESS;
