Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed The open(...) and close(...) primitive are working; they call respectively the MajorFunction[IRP_MJ_CREATE] and MajorFunction[IRP_MJ_CLOSE] of a win32 device driver. But i can't make working correctly any ioctl(...) (it should call MajorFunction[IRP_MJ_DEVICE_CONTROL]), nor write(...) (MajorFunction[IRP_MJ_WRITE]) and read(...)(MajorFunction[IRP_MJ_READ]). Also, the file operation select(...) does not support a file descriptor list where a device driver is in it. Is there a way to achieve that ? Thank you for your help.
