Hi,
I'm about to endeavour into designing a driver interface for my OS
project, and I have some questions about making a type-safe ioctl-like
function.
Since different device types have different sets of ioctl calls it can
accept, I need to be able to have a structure that I can put different
devices into, implying the enumerations aren't identical.
Is the best way to achieve this with those polymorphic variants? And
how much does this affect type safety?
Jon
