3/26/2014
The following table shows the default I/O control codes for the notification LED driver.
Programming element |
Description |
|---|---|
IOCTL_NLED_GETDEVICEINFO |
This IOCTL is used to call NLedDriverGetDeviceInfo. |
IOCTL_NLED_SETDEVICE |
This IOCTL is used to call NLedDriverSetDevice. |
IOCTL_NLED_POSTINIT |
This IOCTL is used to notify the platform dependent driver (PDD) that the NLED driver initialization is complete. This function is only passed to the PDD if gpfnNledPddIOControl is overwritten. |
Note
To create and interpret your own IOCTLs, overwrite gpfnNledPddIOControl during PDD initialization. Any IOCTLs that are not recognized by the model device driver (MDD) are passed onto this function if it has been overwritten.
