Thread: Making my own version of the scanf() version

Hi guys,

This is sort of two questions in one really XD.

I'm trying to make an OS using C. Which is a real challenge as I'm more of a C++ kinda guy, anyway.

How would I be able to create a scanf() type function? The reason I'm asking is because, as you may know, when making an OS you can't include system headers ( you know the #include < > ones ). Is there a way of doing this without the system headers?

And a second, less important question is, how would I be able to incorporate C++ into the C kernel? I.e. make a c++ function, and then call it from within the C main() function? ( If this can be answered then it could make my life easier with the scanf problem as I could use std::cin instead. ).

Thanks in advance.

Jamie.

You have no business making a kernel.

You are so incredibly not ready for the task you've set yourself.

Pull your head from your ... and read a book on programming.

in the C++ file you declare your function 'extern "C" <function declaration>'. this tells the C++ compiler to use C linkage. then a C program can call it. it has to be a plain old function and it can't use any C++ features in the function declaration.
