Function call is not working

[was547]

Hi, I'm trying to call inside lua an C function that contains 2 arguments, but it doesn't works properly, the output give me the error: "error in error handling".

The function have 1 int argument and 1 std::string argument, see:

sel::State lua;
lua.Load(strfmt("../../Scripts/%d.lua", item->PackageId));
lua["SendClientMsg"] = std::function<void(int, std::string)>(SendClientMessage);
int ret = lua["onUse"](m_buffer->Protocol.Connection);

I've tried also in this way:

lua["SendClientMsg"] = &SendClientMessage;

but both ways doesn't work, anyone have a solution to make this work?

the SendClientMessage:

void SendClientMessage(int32_t connectionId, std::string message)

lua file:

function onUse(connId)
    SendClientMessage(connId, "Hello World")
    return 1
end

thanks!

In your code, sel::State lua doesn't know your function SendClientMsg when you loaded your script.
You shall bind your function first then you can load your script.
