[UWP][C++\CX]Calling DeviceIoControl in Background Task RRS feed

  • Question

  • I'd like to try use our customer GPIO driver in UWP.
    I made C# UWP UI code and added C++/CX Background Task.
    Can I use DeviceIoControl API in UWP C++/CX Background Task?
    If I used the DeviceIoControl API, VS2015 made an error "identifier "DeviceIoControl" is undefined. 
    plz anyone help me :)

  • Hello Noir Ryu,

    It seems I can reproduce the undefined error when I use Deviceaccess.h and call the DeviceIoControl function.

    I haven't find any document about whether we can use it in  C++/CX Background Task or which is the right way to use this function in C++\CX. Now how you write your code in your project?

    I will try involve some others on this issue.

    Best regards,

    Barry
