How to Convert Between Pointer Types with unsafe

Use unsafe.Pointer as an intermediate type to convert between incompatible pointer types, bypassing Go's type safety checks.

import "unsafe"

// Convert *int to *byte
var pInt *int
var pByte *byte = (*byte)(unsafe.Pointer(pInt))

// Convert *byte back to *int
var pInt2 *int = (*int)(unsafe.Pointer(pByte))

Converting between pointer types with unsafe forces Go to treat the memory address of one variable as if it were a different type. It is like telling the computer to read the same house number but interpret the contents as a different kind of furniture. Use this only when you are absolutely sure the memory layout matches, as it can cause crashes if done incorrectly.
