DeviceIOControl

    Has anyone come across problems using this function before?
    The application normally works grand in both 2k and NT using the DeviceIOControl function call in a win32 environment.
    However with one particular file the application crashes when I send the request down.
    I'm guessing that it's something to do with the transfer size but I've tried splitting it up into smaller segements and that didn't work either.

    Any suggestions at all would be appreciated.

    Have you tried looking up MSDN?.

    Which language are you using to access the API?

    What device driver are you sending the request to?

    Sorry for all the Q's but the more info you provide the quicker someone can come up with an answer.

    Tried MSDN, no luck. Told me what the function is and what it does but no more
    C++
    Using Windows drivers I think, don't have any of our own anyway.
