Porting From WDM to WDF

NTDEV
1

Hi,

I have a working WDM source code for my USB device. I started converting WDM code to WDF. I am using all the wdf API’s equivalant to the WDM. I am using the WDFrequest for IOcontrolls instead of the IRP’s.
Do i need to convert the WDFREquest to IRP’S?

Tell me whether I am following a currect way or not? Suggest easy tips to convert fastly.

No. The WDFREQUEST contains the IRP, and will manage it for you.
