We could use these 4 bits to mark the table entry with extra information. For example, bit 0 might mean read only, bit 1 might mean dirty (the table entry needs to be updated), and so on. If pointers are 16-bit values, then: 0x3421 is a read-only pointer to the table_entry at address 0x3420; 0xf472 is a pointer to a dirty table_entry at address ...
The list starts out with a single node, the sentinel node which has the next and previous pointers point to itself. This condition determines if the list is empty. In a non-empty list, the sentinel node's next pointer gives the head of the list, and the previous pointer gives the tail of the list.
An autorelative pointer is a pointer whose value is interpreted as an offset from the address of the pointer itself; thus, if a data structure has an autorelative pointer member that points to some portion of the data structure itself, then the data structure may be relocated in memory without having to update the value of the auto relative ...
In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations. It is often a component of more complex analyses such as escape analysis. A closely related technique is shape analysis.
Pointers may also be declared for pointer data types, thus creating multiple indirect pointers, such as char ** and int ***, including pointers to array types. The latter are less common than an array of pointers, and their syntax may be confusing:

Null pointer for indicating the end of a linked list or a tree. A set most significant bit in a stream of equally spaced data values, for example, a set 8th bit in a stream of 7-bit ASCII characters stored in 8-bit bytes indicating a special property (like inverse video, boldface or italics) or the end of the stream.
