At least MacOS X drivers are developed in a subset of C++ http://developer.apple.com/library/mac/#documentation/DeviceDrivers/Conceptual/IOKitFundamentals/Introduction/Introduction.html#//apple_ref/doc/uid/TP0000011-CH204-TPXREF101
Symbian is fully C++ with some assembly So there are at least two comercial OS using C++ to write kernel drivers. If we take Modula2+, Modula-3 and Oberon family of languages into consideration, there are quite a few OS using higher level languages to write their drivers, even if the OS were mostly used inside research labs. I am sure there are a few more examples available. So I don't see an issue with D. -- Paulo "bearophile" <[email protected]> wrote in message news:[email protected]... > An article about the problems in using C++ to write Windows drivers, "C++ > for Kernel Mode Drivers: Pros and Cons" (February 2007): > http://msdn.microsoft.com/en-us/windows/hardware/gg487420.aspx > > The article shows why C++ is not so fit for this purpose.
