BOOLEAN
SetupDiDeleteDeviceInfo(
IN HDEVINFO DeviceInfoSet,
IN PSP_DEVINFO_DATA DeviceInfoData
);
SetupDiDeleteDeviceInfo deletes a member from the specified device information set. This function does not delete the actual device.
The function returns TRUE if it is successful. Otherwise it returns FALSE and the logged error can be retrieved with a call to GetLastError.
If the specified device information element is in use (for example, by a wizard page), the function fails. In this case, a call to GetLastError returns ERROR_DEVINFO_DATA_LOCKED. This happens if a handle to a wizard page is retrieved with a call to SetupDiGetWizardPage with this device information element specified and the DIWP_FLAG_USE_DEVINFO_DATA flag set. To delete this device information element, you must first close the wizard’s HPROPSHEETPAGE handle.
