CBaseFilter.EnumPins method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The EnumPins method enumerates the pins on this filter. This method implements the IBaseFilter::EnumPins method.
Syntax
HRESULT EnumPins(
IEnumPins **ppEnum
);
Parameters
-
ppEnum
-
Address of a variable that receives a pointer to the IEnumPins interface.
Return value
Returns one of the following HRESULT values.
| Return code | Description |
|---|---|

Success |

Insufficient memory |
|
NULL pointer argument |
Remarks
This method creates an instance of the CEnumPins base class, and returns a pointer to that object, of type IEnumPins. The CEnumPins class calls the filter's CBaseFilter::GetPin method to enumerate the pins on the filter.
If this method succeeds, the IEnumPins interface has an outstanding reference count. The caller must release the interface.
