All platform APIs are in C and not C++. The main reason IMO is the lack of standardization of C++ ABI. This is not such an obvious problem if you always only use single compiler, but the main difference between C and C++ after all the language sugar has been removed is that C++ binaries on a single platform, compiled on two different compilers beyond their C like aspects are only accidentally compatible. On some platforms you can make even single compiler builds in C++ incompatible if you use stl - e.g. a stl::vector may be quite different in debug and release build which leads naturally to faulty memory acceess.
