48 error

[andrey231]

Hello, what's my mistake? I use visual studio community edition 2022, c++17

1. vcpkg install uvw:x64-windows
2. Include directories - C:\Users\andre\vcpkg\packages\uvw_x64-windows\include;C:\Users\andre\vcpkg\packages\libuv_x64-windows\include;$(IncludePath)
3. Library directories - C:\Users\andre\vcpkg\packages\libuv_x64-windows\lib;$(LibraryPath)
4. Additional dependencies - uv.lib;%(AdditionalDependencies)
5. Run code example

#include <uvw.hpp>
#include <memory>

void listen(uvw::loop &loop) {
    std::shared_ptr<uvw::tcp_handle> tcp = loop.resource<uvw::tcp_handle>();

    tcp->once<uvw::listen_event>([](const uvw::listen_event &, uvw::tcp_handle &srv) {
        std::shared_ptr<uvw::tcp_handle> client = srv.parent().resource<uvw::tcp_handle>();

        client->on<uvw::close_event>([ptr = srv.shared_from_this()](const uvw::close_event &, uvw::tcp_handle &) { ptr->close(); });
        client->on<uvw::end_event>([](const uvw::end_event &, uvw::tcp_handle &client) { client.close(); });

        srv.accept(*client);
        client->read();
    });

    tcp->bind("127.0.0.1", 4242);
    tcp->listen();
}

void conn(uvw::loop &loop) {
    auto tcp = loop.resource<uvw::tcp_handle>();

    tcp->on<uvw::error_event>([](const uvw::error_event &, uvw::tcp_handle &) { /* handle errors */ });

    tcp->once<uvw::connect_event>([](const uvw::connect_event &, uvw::tcp_handle &tcp) {
        auto dataWrite = std::unique_ptr<char[]>(new char[2]{ 'b', 'c' });
        tcp.write(std::move(dataWrite), 2);
        tcp.close();
    });

    tcp->connect(std::string{"127.0.0.1"}, 4242);
}

int main() {
    auto loop = uvw::loop::get_default();
    listen(*loop);
    conn(*loop);
    loop->run();
}

7. I get 48 errors

It's not tcp->once, it's tcp->on. I just realized that there is a typo in the example. The updated version works just fine locally with VS and C++17.
