Can user mode driver read/write IO and set DMA channel ? What is the difference between traditional user mode driver and new UMDF ? Thank for your teaching .

What is "traditional user mode driver"? I cannot understand this. UMDF's advantage is that the device is properly integrated to the OS's framework of supporting this kind of devices (so all apps written to this MS's framework will be able to use the device). This is how UMDF driver differs from the user-mode DLL. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com |
