	Pointing breed - Wikipedia, the free encyclopedia
		The name pointer most likely comes from the dog's stance when they locate game; many dogs point naturally at interesting noises or possible prey by lifting one paw and tucking it under their chests, with their nose extended and tail straight behind.
		Pointers were selectively bred for dogs who had this natural trait.
		As an example, German Shorthair Pointers are often used to retrieve birds duck hunting whereas, calling upon an English pointer to do the same would be highly unusual.

	Pointers - MYCPLUS (Site not responding. Last check: 2007-11-07)
		A pointer is a variable that represents the location of a data item, such as a variable or an array element.
		Pointers provide a way to return multiple data items from a function via function arguments to be specified as arguments to a given function.
		Pointers are also closely associated with arrays and therefore provide an alternate way to access individual array elements.

		Another good use for pointers to pointers is in dynamically allocated, simulated multidimensional arrays, which we'll discuss in the next chapter.
		As a final example, let's look at how pointers to pointers can be used to eliminate a nuisance we've had when trying to insert and delete items in linked lists.
		Since this pointer points at the pointer that points at the node we're looking at (got that?), it points at the pointer which we need to modify if the node we're looking at is the node we're deleting.

		A high-tech alternative to the retractable, metal pointer, the laser pointer beam will produce a small dot of light on whatever object at which it is aimed.
		Pointers are also used for other purposes such as the aligning of other lasers, laying pipes in construction, and as aiming devices for firearms.

		Pointers are often thought to be the most difficult aspect of C. It's true that many people have various problems with pointers, and that many programs founder on pointer-related bugs.
		As long as you're careful to ensure that the pointers in your programs always point to valid memory, pointers can be useful, powerful, and relatively trouble-free tools.
		A pointer is a variable that points at, or refers to, another variable.

		Pointer are a fundamental part of C. If you cannot use pointers properly then you have basically lost all the power and flexibility that C allows.
		The reason we associate a pointer to a data type is so that it knows how many bytes the data is stored in.

		A pointer provides an indirect means of accessing the value of a particular data item.

	Cprogramming.com Tutorial: Pointers
		For example, using pointers is one way to have a function modify a variable passed to it.
		Pointers require a bit of new syntax because when you have a pointer, you need the ability to request both the memory location it stores and the value stored at that memory location.
		Moreover, since pointers are somewhat special, you need to tell the compiler when you declare your pointer variable that the variable is a pointer, and tell the compiler what type of memory it points to.

		Pointer to a function are perhaps on of the more confusing uses of pointers in C. Pointers to functions are not as common as other pointer uses.
		However, one common use is in a passing pointers to a function as a parameter in a function call.
		Further examples of standard library and system calls that use pointers to functions may be found in Chapters 15.4 and 19.1.

	What`s the Address? Pointers
		While the syntax of declaring a pointer is almost the same as declaring the variables and constants which store a value rather than an address, the meaning of the data type in the declaration of a pointer is different than in the declaration of those other variables and constants.
		However, with a pointer, the data type in the declaration means something different, namely the data type of another variable (or constant) whose memory address is the value of the pointer.
		When the variable is a pointer, that leftover value is interpreted as another memory address, which the pointer then tries to access when you attempt to use it.

	Embedded.com - References vs. Pointers
		The difference between pointer and reference declarations is noteworthy, but it's not the basis for deciding to use one over the other.
		The big difference between pointers and references is that you must use an explicit operator-the * operator-to dereference a pointer, but you don't use an operator to dereference a reference.
		If the pointer happens to be null at the time of the reference definition, the reference is a null reference.

	Pointers
		A pointer is probably implemented as the main memory address (or some variation on this) of the item to which it points.
		Pointers have been used to implement reference parameters on the run-time stack, arrays names were seen as pointers, and the this pointer was used with objects, just to name three uses.

		The pointer is then a pointer to a variable of that one specific type and should not be used with variables of other types.
		Of course, an experienced C programmer knows that it is simple to coerce the pointer to be used with some other type by using a cast, but he must assume the responsibility for its correct usage.

	Pointers - C# to IL
		A pointer also needs to be typed, so that it can point to memory locations that contain data of the same type.
		Pointer are not interpreted as memory locations to a particular data type, but as numbers.
		The most important thing about this type of pointer is that, it must be reported to the garbage collector, in spite of the fact that, it points to managed memory.

		This chapter discusses smart pointers, from their simplest aspects to their most complex ones and from the most obvious errors in implementing them to the subtlest ones—some of which also happen to be the most gruesome.
		In addition to sporting pointer syntax and semantics, smart pointers often perform useful tasks—such as memory management or locking—under the covers, thus freeing the application from carefully managing the lifetime of pointed-to objects.
		A smart pointer is a C++ class that mimics a regular pointer in syntax and some semantics, but it does more.

	Pointers
		Pointers have been included in Fortran 90, but not in the usual way as in most other languages, with pointer as a specific data type.
		Pointers in Fortran 90 are thus not memory addresses as in other programming languages (and in certain Fortran implementations) but rather an extra name (alias).
		This increases the security at the use of pointers, it is therefore not possible by mistake to let a pointer change values of variables of other (different) data types.

	Smart Software: Pointers
		However, not CLS compliant, pointers do need to work in Reflection, and the framework does provide a mechanism to box pointers through the System.Reflection.Pointer class, which is derived from System.Object.
		On the other hand, the type given by typeof(p), where p is a pointer, is a specially constructed pointer type, distinct from the Pointer type, with no base type (meaning it does not derive from object).
		TypedReference is essentially one of two managed pointer types supported in IL and maintains both the pointer value and the type of the value pointed to.
