当设备收到释放其独占声明的请求时发生。

// Register
event_token ReleaseDeviceRequested(TypedEventHandler<ClaimedCashDrawer, IInspectable const&> const& handler) const;

// Revoke with event_token
void ReleaseDeviceRequested(event_token const* cookie) const;

// Revoke with event_revoker
ClaimedCashDrawer::ReleaseDeviceRequested_revoker ReleaseDeviceRequested(auto_revoke_t, TypedEventHandler<ClaimedCashDrawer, IInspectable const&> const& handler) const;
public event TypedEventHandler<ClaimedCashDrawer,object> ReleaseDeviceRequested;
function onReleaseDeviceRequested(eventArgs) { /* Your code */ }
claimedCashDrawer.addEventListener("releasedevicerequested", onReleaseDeviceRequested);
