typedef struct _DMUS_IO_TOOL_HEADER {

    long    lIndex;
    DWORD   cPChannels;
    FOURCC  ckid;
    FOURCC  fccType; 
    DWORD   dwPChannels[1]; 
} DMUS_IO_TOOL_HEADER;

guidClassID

Class identifier of the tool.

lIndex

Position in the graph.

cPChannels

Number of items in the dwPChannels array.

ckid

Identifier of tool's data chunk. If this value is 0, it is assumed that the chunk is of type LIST, so fccType is valid and must be nonzero.

fccType

List type. If this value is 0, ckid is valid and must be nonzero.

dwPChannels

Array of performance channels for which the tool is valid.
