#include <pyawaitable.h>

// Assuming that this is using METH_O
static PyObject *
hello(PyObject *self, PyObject *coro) {
    // Make our awaitable object
    PyObject *awaitable = pyawaitable_new();

    if (!awaitable)
        return NULL;

    // Mark the coroutine for being awaited
    if (pyawaitable_await(awaitable, coro, NULL, NULL) < 0) {
        Py_DECREF(awaitable);
        return NULL;
    }

    // Return the awaitable object to yield to the event loop
    return awaitable;
}

# Assuming top-level await
async def coro():
    await asyncio.sleep(1)
    print("awaited from C!")

# Use our C function to await it
await hello(coro())
