IOCTL_INTERNAL_I8042_MOUSE_START_INFORMATION IOCTL

  • 2 minutes to read

The IOCTL_INTERNAL_I8042_MOUSE_START_INFORMATION request passes a pointer to a mouse interrupt object. I8042prt sends this request synchronously to the top of the device stack after the mouse interrupt object is created. Upper-level filter drivers that need to synchronize their callback operation with the mouse ISR can use the pointer to the mouse interrupt object.
