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. For more information, see %_WINCEROOT%\Public\Common\SDK\Inc\nled.h and Stream Interface Drivers.
