bytes2ptr (buf)
The bytes2ptr function converts the array of characters in buf to a Pointer and returns a reference to it. The buf array should consist of exactly Size bytes and be in the format returned by /dev/pointer. ptr2bytes (ptr)
The ptr2bytes function provides an inverse transformation of the bytes2ptr function. Files
