A slot is a narrow opening. It can be used for receiving signals, for example.

In a vending machine, the slot can be slit for a coin. Slots are also used to manage air traffic in busy airports.

In sports, a high slot is the prime place for a defenseman to take a shot. The low slot is the area in front of a goaltender. He or she can then place a stick out in front of the goalie to redirect a shot.

Slots can be invoked from any component. They follow normal C++ rules when called directly. If a slot is expecting a signal, it will report a runtime error.

Slot-based scheduling can be used by health care providers and financial consultants. For instance, a financial consultant may use scheduling software to keep track of appointments, and set deadlines.

Some modern slot machines have advanced bonus rounds. These can include a variety of video graphics. Bonus features are typically aligned with the theme of the game.

Slots can be invoked from a function pointer. However, the connection is based on a signal, and should be emitted from a class that defines the signal.
