Typedef Documentation

typedef bool(* Zygoma::ia32::InterruptHandlerTrampoline)(int interruptNumber)

The type of the trampoline function for invoking an interrupt handler from an interrupt gate.

typedef VgaStreambuf<char> Zygoma::ia32::KStreamBuf

typedef unsigned long Zygoma::ia32::PhysicalAddress

A physical address in the memory space. The Physical Address is what's sent out along the physical address buf after all the logical and linear mapping has been done through the page table and segmentation and tar and feathers provided by the system to hide the physical addresses from the programmer.
