Listen for input and get metadata about the event. If Independent Input Source is enabled then these events will not work

C#
using CI.WSANative.Input;

Initialise must be called first - it need only ever be called once

C#
WSANativeInput.Initialise();

C#
WSANativeInput.PointerPressed += (e) =>
{
    if (e.InputType == WSAInputType.Pen)
    {
    }
});

C#
WSANativeInput.PointerReleased += (e) =>
{
    if (e.InputType == WSAInputType.Pen)
    {
    }
});
