IPortableDevice Interface
The IPortableDevice interface provides access to a portable device.
To create and open this interface, first call CoCreateInstance with CLSID_PortableDevice to retrieve an IPortableDevice interface, and then call IPortableDevice::Open to open a connection to the device.
In addition to the methods inherited from IUnknown, the IPortableDevice interface exposes the following methods.
| Method | Description |
| Advise | Registers an application-defined callback that receives device events. |
| Cancel | Cancels a pending operation on this interface. |
| Capabilities | Retrieves an interface used to query the capabilities of a portable device. |
| Close | Closes the connection with the device. |
| Content | Retrieves an interface used to access objects on a device. |
| GetPnPDeviceID | Retrieves a Plug and Play (PnP) identifier used to open a device. |
| Open | Opens a connection between the application and the device. |
| SendCommand | Sends a command to the device and retrieves the results synchronously. |
| Unadvise | Unregisters a client from receiving callback notifications. |
Remarks
The client interfaces are designed to be used for any WPD object; it is not necessary to create a new instance for each object referenced by the application. After an application opens an instance of the IPortableDevice interface, it should open and cache any other WPD client interfaces that it will require.
Requirements
