  • Article

The I2C_CALLBACKS structure contains pointers to functions, implemented by the video miniport driver, that read from and write to the serial data and serial clock lines of the I2C bus.

Syntax

typedef struct _I2C_CALLBACKS {
  IN PVIDEO_WRITE_CLOCK_LINE WriteClockLine;
  IN PVIDEO_WRITE_DATA_LINE  WriteDataLine;
  IN PVIDEO_READ_CLOCK_LINE  ReadClockLine;
  IN PVIDEO_READ_DATA_LINE   ReadDataLine;
} I2C_CALLBACKS, *PI2C_CALLBACKS;
