# w32coro

Small hand-written coroutines library. Written in C++14 with Win32 API (Fibers).

## Examples

#### Receiving some information from server

```cpp

#include "w32coro/w32coro.h"

#include "MyAwesomeProject.h"

int main()

{

    const auto ReceiveData = [](const std::wstring& wsServerName, DWORD dwPort) {

        IConnectionPtr spConn = Connect(wsServerName, dwPort);

        std::wstring wsData = spConn->Receive();

        

        w32coro::CoReturn(wsData);

    };

    

    std::wstring wsServerName = L"my.awesome.server";

    DWORD dwPort = 8080;

    

    const auto wsReceivedData = w32coro::CoAwait(

        w32coro::Coroutine(ReceiveData, std::cref(wsServerName), dwPort));

        

    std::wcout << wsReceivedData << std::endl;

}

```

#### Suspending, resuming and returning various values

Actually this example can be extended to write real generator, that implements some methods such as `begin` and `end` to use it in range-based for loop.

```cpp

#include "w32coro/w32coro.h"

#include "MyAwesomeProject.h"

int main()

{

    const auto Generate = [](size_t Initial) {

        while (true) {

            w32coro::CoYield(Initial++);

        }

    };

    

    w32coro::Coroutine gen(Generate, 0);

    

    std::vector Numbers;

    for (size_t i = 0; i < 10; i++) {

        Numbers.emplace_back(gen.Get());

        gen.Resume();

    }

    

    //

    // Will print 0 1 2 ...

    //

    for (size_t n : Numbers) {

        std::cout << n << ' ';

    }

}

```
