Castling is a composite move of King and Rook at the same time. In standard chess it consists of moving a king two squares towards the rook and executing a jump of a rook over the king.
Marina Kalinovsky, Castling, 1961 [1]

Rules

The prequisites for doing it are as follows:
  • the king and the relevant rook must not be moved, considered as castling rights inside a chess position
  • the king must not be in check
  • no square between king's start and final square may be controlled by the enemy

Chess960

In Chess960 castling is a move reaching the position just like after standard chess castling, which may be achieved by (a) moving the king to c1 or g1 ant then executing a jump by relevant rook (b) jumping with the rook over a king already placed on c1 or g1 (c) interchanging the positions of king and rook [2].

Shogi

A formation achieved after castling is called a castle. This is often contrasted with a castle in the game of Shogi, requiring several moves to complete, but it seems wrong, since chess also has several standard defensive castle formations - like the one after fianchetto of a king's bishop or the one with a knight on g7, often achieved in the Old Benoni. For that reason it might be interesting to use shogi programming concepts of a castle map and an attack map in chess.
