IDE_CHANNEL_INTERFACE structure (irb.h)
The IDE_CHANNEL_INTERFACE structure contains interface information for the indicated channel.
Note
The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
Syntax
typedef struct _IDE_CHANNEL_INTERFACE {
USHORT Version;
UCHAR ChannelNumber;
UCHAR Reserved;
ULONG ReservedUlong;
IDE_HW_INITIALIZE IdeHwInitialize;
IDE_HW_BUILDIO IdeHwBuildIo;
IDE_HW_STARTIO IdeHwStartIo;
IDE_HW_INTERRUPT IdeHwInterrupt;
IDE_HW_RESET IdeHwReset;
IDE_HW_CONTROL IdeHwControl;
} IDE_CHANNEL_INTERFACE, *PIDE_CHANNEL_INTERFACE;
Members
Version
The port driver sets this member to sizeof(IDE_CHANNEL_INTERFACE). The miniport driver should verify that the version is greater than or equal to the one it is using.
ChannelNumber
The port driver sets this field to the number assigned for this channel. For non-native mode controllers, the primary channel will always be assigned 0 and the secondary channel will always be assigned 1.
Reserved
Reserved. The miniport driver must not use this field.
ReservedUlong
Reserved. The miniport driver must not use this field.
IdeHwInitialize
The miniport's IdeHwInitialize routine.
IdeHwBuildIo
The miniport's IdeHwBuildIo routine.
IdeHwStartIo
The miniport's IdeHwStartIo routine.
IdeHwInterrupt
The miniport's IdeHwInterrupt routine.
IdeHwReset
The miniport's IdeHwReset routine.
IdeHwControl
The miniport's IdeHwControl routine.
