A beginner's question

NTDEV

Hi all,

I just wanted to ask for some advise since I am still new in the driver architecture.
I ve created a simple usb driver and now I want to make some of its functionality
available to user mode software applications. (a.k.a create an API).
How does a certain function can be exported (published) to software applications?
And how does a software application accesses the driver’s API?
Can someone give me some general advice on what to read on this issue?
Thanks

First, please don't use html formatting and colors in your postings. People
seem to have problems reading it.

Read about Device Interfaces (IoRegisterDeviceInterface) and IoControl
(IRP_MJ_DEVICE_CONTROL in the kernel and DeviceIoControl for user-mode).

If you have any other question, we'll be there.

Call IoRegisterDeviceInterface and support some IOCTLs.
In user mode, call SetupDiGetClassDevs to find the file name from interface GUID, open this file, then call DeviceIoControl with appropriate IOCTL codes.

I make it a point to ignore and just skip those messages. Maybe he could
just use white on white? His choice is not much better.
