I understand the basics of the usage, and that is serves to highlight the purpose of each of the variables passed to functions along with various other things for static code analysis, but how much difference does it actually make (ignoring increasing clarity of parameter requirements for other programmers on the project)? If I was to have the following prototype:

These have no real affect on compilation (under VS 2010 they aren't even expanded), they are there for inline API documentation. __in : this parameter is an input to the function (read-only, caller initialized). __out : this parameter
