I am running a C code to respond to a circuit to control electrical appliance with mangw on windows 8 and am getting an error with the outportb error

If you want someone to help you fix your code, you need to show your code.

Click "Improve question" and update your question with the relevant parts of your code.

Check for some mistyping around outportb. Maybe you better use "(" instead of "<".

This tells us that you copied the code off the internet but you have no idea how it works.

"mangw"? Never heard of it. Don't know what it is.

Windows abstracts all the hardware from your code. You do not have the ability to directly manipulate ports without a kernel driver.
