The Create method creates a new media with default properties, adds it to the collection at the specified index, and returns a pointer to the ITMedia interface.

Syntax

HRESULT Create(
  [in]  LONG    Index,
  [out] ITMedia **ppMedia
);

Parameters

Index [in]: Index for the new item. The minimum value for the index is 1, and the maximum value for the index is the current number of items + 1.
ppMedia [out]: Pointer to ITMedia interface created.

Return value

This method can return one of these values.

Value	Meaning
S_OK	Method succeeded.
E_POINTER	The ppMedia parameter is not a valid pointer.
E_INVALIDARG	The Index parameter is not valid.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.
E_FAIL	Unspecified error.
E_NOTIMPL	This method is not yet implemented.

Remarks

Most C and C++ lists are 0-based, but this index is 1-based for Visual Basic compatibility, meaning the first item has an index number of 1.

TAPI calls the AddRef method on the ITMedia interface returned by ITMediaCollection::Create. The application must call Release on the ITMedia interface to free resources associated with it.
