current macOS man pages are kind of off-putting, even for someone who has been using c and unix for decades. I mean, really, what is this?

    InFILE In*
     fopen(Inconst Inchar In* Inrestrict Inpath, Inconst Inchar In* Inrestrict Inmode);

Inconst InFILE In* Inrestrict Inpath?!

     FILE *fopen(const char *, const char *mode);

it's like looking at a ton of gibberish and trying to figure out what it says. it doesn't match the languages, it doesn't appear to match any standards.

I learned a lot from man pages in the 80's and 90's, and if I had to try to learn now from something like this, I'd likely just throw up my hands and choose another career.
