What is the difference between near, far and huge pointers in C Language?
A virtual address is composed of the selector and offset.
A near pointer doesn’t have explicit selector whereas far, and huge pointers have explicit selector. When you perform pointer arithmetic on the far pointer, the selector is not modified, but in case of a huge pointer, it can be modified.
These are the non-standard keywords and implementation specific. These are irrelevant in a modern platform.
