Overlapped I/O operation is in progress Issue RRS feed

  • Question

  • Hi Team,

    We have written windows application for read&write data from I2C device.

    Here,we used FILE_FLAG_OVERLAPPED flag for hdevice opening,we can open device successfully. 

    After that we called DeviceIoControl API with Overlapped structure(asynchronous) for writing data into device.

    But that API return status as ZERO(0x00), Meantime we checked Error code using GetLastError() method, it return error code as 0X3e5(Overlapped I/O operation is in progress).

    Kindly give your valuable suggestion,how can we Fix this error.


    OS : Win7

    Platform : Baytrail


    Thanks& Regards,
