Hooking

In computer programming, the term hooking covers a range of techniques used to alter or augment the behavior of an operating system, of applications, or of other software components by intercepting function calls or messages or events passed between software components. Code that handles such intercepted function calls, events or messages is called a "hook".

Hooking is used for many purposes, including debugging and extending functionality. Examples might include intercepting keyboard or mouse event messages before they reach an application, or intercepting operating system calls in order to monitor behavior or modify the function of an application or other component. It is also widely used in benchmarking programs, for example frame rate measuring in 3D games, where the output and input is done through hooking.

Hooking can also be used by malicious code. For example, rootkits, pieces of software that try to make themselves invisible by faking the output of API calls that would otherwise reveal their existence, often use hooking techniques. A wallhack is another example of malicious behavior that can stem from hooking techniques. It is done by intercepting function calls in a computer game and altering what is shown to the player to allow them to gain an unfair advantage over other players.

Hooking (ice hockey)

Hooking in ice hockey is a penalty. The NHL covers hooking in Rule 55, which defines it as "the act of using the stick in a manner that enables a player or goalkeeper to restrain an opponent." The NHL groups hooking with other "Restraining fouls" such as holding, interference and tripping.[1]

Hooking in the rules

The NHL covers hooking in Rule 55, which defines it as "the act of using the stick in a manner that enables a player or goalkeeper to restrain an opponent." It goes on to specify that "when a player is checking another in such a way that there is only stick-to-stick contact, such action is not to be penalized as hooking." The NHL groups hooking with other "Restraining fouls" such as holding, interference and tripping.

The IIHF covers hooking in Rule 533, defining a player guilty of hooking as one "who impedes or seeks to impede the progress of an opponent by hooking him with the stick."

Both codes allow for hooking to be penalized with either a minor or major penalty; the latter is imposed for injuring an opponent by hooking, and carries with it an automatic game misconduct.
