DeviceIOControl

[elgohary]

I am using BCB6. I need to use the WIN32 API function DeviceIOControl() in order to communicate with a USB driver. I have included windows.h, winioctl.h, winbase.h(where it is declared), and dbt.h.

Here is my problem: When I build my project it get the following error.
[C++ Error] MyForm.cpp(48): E2268 Call to undefined function 'DeviceIOControl'

Any comments are much appreciated. Thank you.

I don't think the problems are related. If my problem were to be with the dll then I would get a linker error. I get a compiler error. I think that it is having a problem finding the declaration, which is in winbase.h. Thanks for you comment.

Sometimes I want to kick myself in the pants...

The function name is DeviceIoControl(...), not DeviceIOControl(...). Thanks for your comment 2ffat.
