IEnumFilters::Skip method (strmif.h)

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Skip method skips over a specified number of filters.

Syntax

HRESULT Skip(
  [in] ULONG cFilters
);

Parameters

[in] cFilters

Number of filters to skip.

Return value

Value	Description
S_FALSE	Skipped past the end of the sequence.
S_OK	Success.
VFW_E_ENUM_OUT_OF_SYNC	The graph has changed and is now inconsistent with the enumerator.

Remarks

If the filter graph changes (for example, the application removes a filter), the enumerator is no longer be consistent with the graph, and the method returns VFW_E_ENUM_OUT_OF_SYNC. Discard any data obtained from previous calls to the enumerator, because it might be invalid. Update the enumerator by calling the IEnumFilters::Reset method. You can then call the Skip method safely.
