IEnumMediaTypes::Skip

The Skip method skips over a specified number of media types.

Syntax

  HRESULT Skip(
  ULONG cMediaTypes
);

Parameters

cMediaTypes

[in] Number of media types to skip.

Return Values

Returns one of the following HRESULT values.

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

Remarks

If the set of media types changes, the enumerator is no longer consistent with the pin, 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 IEnumMediaTypes::Reset method. You can then call the Skip method safely.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
