1:58:36ivereadthesequel Q: Speaking about MSDN, I had an issue where an old version of docs had a remark that was important for a certain call, that some value should be set a certain way in a struct. Not there in the new version. ACKK!! Anyway, doesn't the "remarks" section usually have information on things like "CloseFile" for the "CreateFile" call and so on?

2:07:35Brian Q: Greetings Casey. How do you find balancing duplicating code versus trying to generalize a function? As an exercise, I took FormatString() – from Handmade Hero – and wrote a FormatWideString() version. In the end I chose to simply take the format, call UTF8FromUTF16(), call FormatString() on a temp buffer, then UTF16FromUTF8(). But now I sacrifice performance for maintenance. Other than if it becomes a bottleneck when profiling, what other things do you look for choosing to duplicate code and making it more a pain to maintain, than the benefits of having specific versions?
