3/26/2014
This method records the details of the pin in the registry.
Syntax
HRESULT RegisterPin(
CLSID Filter,
LPCWSTR Name,
BOOL bRendered,
BOOL bOutput,
BOOL bZero,
BOOL bMany,
CLSID ConnectsToFilter,
LPWSTR ConnectsToPin
);
Parameters
- Filter
[in] Globally unique identifier (GUID) of the filter.
- Name
[in] Name of the pin. This should be unique within the filter. It has no significance other than to indicate type information. Note that pin names longer than 99 characters should not be used, because this causes filter enumeration problems.
- bRendered
[in] Set to TRUE if the filter renders this input; otherwise, set to FALSE.
- bOutput
[in] Set to TRUE if this is an output pin; otherwise, set to FALSE.
- bZero
[in] If the filter can have zero instances of this pin, set to TRUE; otherwise, set to FALSE. For example, a decompression filter might choose to not create a sound output pin for a movie without a sound track.
- bMany
[in] If the filter can have many instances of this pin, set to TRUE; otherwise, set to FALSE. For example, a mixer might have multiple instances of its input pin.
- ConnectsToFilter
[in] Reserved. Must be NULL. (This is intended for filters such as system-wide mixers that have connections outside the filter graph. It is not yet implemented.)
- ConnectsToPin
[in] Reserved. Must be NULL.
Return Value
Returns an HRESULT value.
