Which end of a bit field is the most significant bit?

Question

I\'m writing a C++ application for Windows XP/Vista/7 using Visual Studio 2008. Some of my structures use a bit field, as shown in the example.

typedef stru         


        

Answer 1

The Visual Studio 2008 compiler docs indicate:

The ordering of data declared as bit fields is from low to high bit
