C Pointers

Up until now, we have used the following kinds of pointers:

• single item pointers - *T
• many item pointers - [*]T
• slices - []T

Unlike the aforementioned pointers, C pointers cannot deal with specially aligned data and may point to the address 0. C pointers coerce back and forth between integers, and also coerce to single and multi item pointers. When a C pointer of value 0 is coerced to a non-optional pointer, this is detectable illegal behaviour.

Outside of automatically translated C code, the usage of [*c] is almost always a bad idea, and should almost never be used.
