REGPINMEDIUM Structure

Describes a pin medium (as defined in the Windows NT DDK) for registration through the IFilterMapper2 interface.

Syntax

typedef struct
{
    CLSID clsMedium;
    DWORD dw1;
    DWORD dw2;
} REGPINMEDIUM;

Members

clsMedium
Contains the globally unique set identifier.
dw1
Contains the set-specific identifier for an item within the set.
dw2
Used for various set flags. Zero when not used.

Remarks

A medium defines a method of communication (for example, the bus over which the communication occurs). Each ID within that set is used to represent the form of communication. Register mediums for your filter if you need to search for Microsoft® DirectShow® filters built on kernel streaming pins, which can connect to each other.
