wrap around

(Or "wraparound", "wrap") The action of a counter that starts again at zero or at "minus infinity" (see infinity) after its maximum value has been reached, and continues incrementing, either because it is programmed to do so or because of an overflow (as when a car's odometer starts again at 0).

[Jargon File]



Code which is combined with another piece of code to determine how that code is executed. The wrapper acts as an interface between its caller and the wrapped code. This may be done for compatibility, e.g. if the wrapped code is in a different programming language or uses different calling conventions, or for security, e.g. to prevent the calling program from executing certain functions. The implication is that the wrapped code can only be accessed via the wrapper.
