SignalUserCancel Delegate

Namespace: Yubico.YubiKey Assembly: Yubico.YubiKey.dll

This delegate defines the signature of a method that can be called to let the SDK know that the user is canceling an operation.

C#

public delegate void SignalUserCancel()

Remarks

Generally a KeyCollector indicates a user cancels by returning false. However, for some requests, such as TouchRequest and EnrollFingerprint, the KeyCollector's return value is ignored because it is an asynchronous call. In those cases, the SDK will supply an implementation of this delegate that your KeyCollector can call to notify the SDK that the user has canceled.
