IRTCEnumPresenceDevices (Windows Embedded CE 6.0)
1/6/2010
Note
This interface is unsupported in Windows Embedded CE 6.0.
This interface provides COM-standard enumeration methods for the IRTCPresenceDevice interface. The IRTCBuddy2::EnumeratePresenceDevices method gets a pointer to IRTCEnumPresenceDevices. This interface is intended for C and C++ applications and is hidden from Visual Basic applications.
Methods
The following table shows the methods for this interface in vtable order. This is the order in which the compiler calls the methods. Like all COM interfaces, this interface inherits the methods for the IUnknown interface.
| Method | Description |
|---|---|
Retrieves the next specified number of elements in the enumeration sequence. |
|
Resets to the beginning of the enumeration sequence. |
|
Skips the next specified number of elements in the enumeration sequence. |
|
Creates another enumerator that contains the same enumeration state as the current one. |
Remarks
Every time an IRTClient gets a presence update of an IRTCBuddy, it deletes all previous IRTCPresenceDevice objects from the buddy’s internal array and then creates new objects with the updated presence.
Requirements
| Header | rtccore.h, rtccore.idl |
| Library | uuid.lib |
| Windows Embedded CE | Windows CE .NET 4.2 and later |
