winapi - Does QueryDosDevice and IOCTL_STORAGE_GET_DEVICE_NUM treat LUNs as separate devices? -

-

can confirm whether querydosdevice() , ioctl_storage_get_device_number considers luns on same physical usb storage device single device, or each lun considered separate device?

for example, if have usb thumb drive has multiple luns, , each lun has been allocated logical dos "letter", such c:, d:, etc, if call querydosdevice() return same devicename luns? or each lun have different devicename?

similarly, if use ioctl_storage_get_device_number each of luns, returned devicenumber same luns?

thanks help!
