The reason I think correct C type is used is because in the "winscard.h" C header file, the expected type is LPSCARD_READERSTATE. And , in the golang cgo code, i.e. scard_unix.go, the argument 3 is cast as (C.LPSCARD_READERSTATE). *Further details (not sure if is useful): * I found that in

IMO it's simpler to start with all you code in a single package and only break something out when you find three or more cases where the code could be reused. Some other markers I use to guide breaking the code up into separate packages are if you find you have written a significant amount of

Thanks Dave. I hear you about models not being their own package. If I read you correctly, and taking it to the extreme, all files in a micro-service belong in the same package, possibly bar 'main'. If all database access is related to the same 'problem area', it all belongs in the same

That is exactly what I was thinking. I could save the files as OpenDocument format, DocBook format, etc. in Android but in proprietary format in the database where no-one else is looking at except my server. If I use a known standard, like ODT, I actually may need to study a lot of hours to

Hey Axel, this is a good question that I've thought about from time to time as well. It seems that most people in this thread have misunderstood it :) I personally agree with your preference as given in the examples just because I find the code easier to read when the error return is handled

I've always argued that a package's name is a one word elevator pitch for what it provides--not what it contains. Package models fails this tests because it enumerates the contents of the package. You could argue that this also provides the models for your project, but think about what

I'm on Dave C.'s side with this one. Check the error value. If an error is present, all bets are off with regard to any of the return values. It's simple, explicit and consistent. The idea that "sometimes" an API call will return values that "may" be helpful, or partially useful, is a recipe

Apologies if this has already been asked and answered, I'm not quite sure which incantation to put in the google box. In our organisation, we have many private and public go packages for various projects. For each micro-service, we structure it as: /cmd/{name}/{name}.go - something which
