Thanks for that. U was now able to compile a sample driver into a .sys file. I used the SCOpenManager and CreateProcess to get it loaded.

A snippet of the CYGWIN code for win driver is as follows: RtlInitUnicodeString( &DeviceName, L"\\Device\\mydevice" ); RtlInitUnicodeString( &SymbolicLinkName, L"\\DosDevices\\mydevice" ); IoCreateDevice( DriverObject, 0, &DeviceName, ...
