ITAddress::get_Calls method (tapi3if.h)
The get_Calls method creates a collection of calls currently active on the address. This method is provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateCalls method.
Syntax
HRESULT get_Calls(
[out] VARIANT *pVariant
);
Parameters
[out] pVariant
Pointer to a VARIANT containing an ITCollection of ITCallInfo interface pointers (call objects).
Return value
This method can return one of these values.
| Value | Meaning |
|---|---|
|
Method succeeded. |
|
The pVariant parameter is not a valid pointer. |
|
Insufficient memory exists to perform the operation. |
Remarks
TAPI calls the AddRef method on the ITCallInfo interface returned by ITAddress::get_Calls. The application must call Release on the ITCallInfo interface to free resources associated with it.
