The VIDEO_PORT_I2C_INTERFACE structure describes the I2C service routines provided by the video port driver.

typedef struct _VIDEO_PORT_I2C_INTERFACE {
  USHORT  Size;
  USHORT  Version;
  PVOID  Context;
  PINTERFACE_REFERENCE  InterfaceReference;
  PINTERFACE_DEREFERENCE  InterfaceDereference;
  PI2C_START  I2CStart;
  PI2C_STOP  I2CStop;
  PI2C_WRITE  I2CWrite;
  PI2C_READ  I2CRead;
} VIDEO_PORT_I2C_INTERFACE, *PVIDEO_PORT_I2C_INTERFACE;

Members

Size

Specifies the size in bytes of this structure.

Version

Specifies the version of the interface to be returned by the miniport driver. The current interface version is defined in video.h, and has the form VIDEO_PORT_I2C_INTERFACE_N.

Context

Pointer to a miniport driver-defined context for the interface.

InterfaceReference

Pointer to the video port driver-implemented reference routine for this interface.

InterfaceDereference

Pointer to the video port driver-implemented dereference routine for this interface.

I2CStart

Pointer to the video port driver's I2CStart routine.

I2CStop

Pointer to the video port driver's I2CStop routine.

I2CWrite

Pointer to the video port driver's I2CWrite routine.

I2CRead

Pointer to the video port driver's I2CRead routine.

Comments

PnP video miniport drivers that can use I2C should fill in the Size and Version members of this structure, and then call VideoPortQueryServices, which initializes the remaining members of this structure.

Requirements

Headers: Declared in video.h. Include video.h.
