> Seriously, this was a huge thing in C and C++, where you had to know/remember/know to look up very specific error codes and conditions in an API and if you didn't then it was very much considered to be a skill issue.

It was not unless you were part of some very weird circle. There was always manuals and other references that listed everything about a platform or library. Then we got ‘man’ and ‘info’. And I remember being able to download the full docs of windows’ various documentation.

That’s like saying as a writer you were looked down at because you had to look at a dictionary every once in a while.
