I send an IOCTL_MOUNTMGR_VOLUME_ARRIVAL_NOTIFICATION to the Mount Manager DO, and my device object regularly receives an IOCTL_MOUNTDEV_QUERY_DEVICE_NAME, but as output buffer length I can read only 4 bytes from IoStackLocation->Parameters.DeviceIoControl.OutputBufferLength. so (as from documentation) I fill th... 10 Aug 2006 05:06

Assembly Code in 64 bit driver
When I search on the web for pointers on porting a 32 bit driver to 64 bit I get plenty of references to Intrinsic functions and masm files.
