IEnumRegFilters::Next (Windows CE 5.0)
This method fills the array with descriptions of the next set of filters (specified by the cFilters parameter) that meet the requirements specified upon creation of the enumerator.
HRESULTNext(ULONGcFilters,REGFILTER** apRegFilter,ULONG* pcFetched);
Parameters
- cFilters
[in] Number of filters. - apRegFilter
[out] Pointer to an array of REGFILTER pointers. - pcFetched
[out] Actual number of filters passed.
Return Values
Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants or other values not listed.
| Value | Description |
|---|---|
| E_FAIL | Failure. |
| E_POINTER | Null pointer argument. |
| E_INVALIDARG | Invalid argument. |
| E_NOTIMPL | Method is not supported. |
| S_OK or NOERROR | Success. |
Remarks
The calling application must use the Win32 CoTaskMemFree function to free each REGFILTER pointer returned in the array.
Do not free the Name member of the REGFILTER structure separately. IEnumRegFilters::Next allocates memory for this string as part of the REGFILTER structure.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
