tips

on mac OS 10.12+, the ucontext.h was deprecated so you can use sys/ucontext.h or debug it. I test it and debug module is ok.

test

void test1()
{
    for (int i = 0; i < 5; ++i) {
        std::cout << "test 1 => " << i << std::endl;
        coroutine::yield();
    }


}

void test2()
{
    for (int i = 0; i < 5; ++i) {
        std::cout << "test 2 => " << i << std::endl;
        coroutine::yield();
    }
}

void test()
{
    size_t co1 = coroutine::create(test1);
    size_t co2 = coroutine::create(test2);
    std::cout << "test start" << std::endl;
    while (coroutine::getStatus(co1) != coroutine::kCoroutineStatus::Dead && coroutine::getStatus(co2) != coroutine::kCoroutineStatus::Dead)
    {
	coroutine::resume(co1);
	coroutine::resume(co2);
    }

    coroutine::destroy(co1);
    coroutine::destroy(co2);
    std::cout << "test end" << std::endl;
}

output:

Two coroutines alternate in parallel in the main thread, no context switching about thread and Low overhead.

test start
test 1 => 0
test 2 => 0
test 1 => 1
test 2 => 1
test 1 => 2
test 2 => 2
test 1 => 3
test 2 => 3
test 1 => 4
test 2 => 4
test end
