The Next method retrieves a specified number of pins in the enumeration sequence. This method implements the IEnumPins::Next method.
HRESULT Next( ULONG cPins, IPin **ppPins, ULONG *pcFetched );
Number of pins to retrieve.
Array of size cPins that is filled with IPin pointers.
Pointer to a variable that receives the number of pins retrieved. Can be NULL if cPins is 1.
Returns one of the HRESULT values shown in the following table.
|S_FALSE||Did not retrieve as many pins as requested.|
|E_POINTER||NULL pointer argument.|
|VFW_E_ENUM_OUT_OF_SYNC||The filter's state has changed and is now inconsistent with the enumerator.|
This method retrieves pointers to the specified number of pins, starting at the current position in the enumeration, and places them in the specified array.
This method calls the filter's CBaseFilter::GetPin method to retrieve the pins.
If the method succeeds, the IPin pointers all have outstanding reference counts. Be sure to release them when you are done.
