I don't fully understand everything I am reading in this book. Maybe this is an error that has not been added to the Errata sheet. You can submit an error via an errata form ( https://hub.wiley.com/community/support/wrox )and the author or his people will attempt to verify the error and add it to the errata sheet.

hope this helps

Hi Brian,

If you've had a go at Ex11_01 you'll probably have the code available inside Visual Studio. If you right-click on WINAPI and select 'Go to definition' it will bring up 'windef.h'.

In here you can see that if you are compiling on a Windows system, as opposed to a Mac or something else, WINAPI is defined as '__stdcall'. Directly above it you can see that CALLBACK is defined as exactly the same thing.

So it shouldn't make any difference to the compilation process. If you're supposed to use one or the other for code readability purposes I couldn't tell you.

Hope this is helpful.
