Re: bug in example in http://man7.org/linux/man-pages/man7/pkeys.7.html void -> int

[Michael Kerrisk (man-pages)]

Hello Aaron,

I'm sorry. I don't understand your bug report. As far as I can see,
the manual page never looked like the text you quote. But, maybe I
misunderstand you?

Thanks,

Michael

I think Aaron's point is that if you tried to compile the example 
program, you would get:

   pkeys.c: In function ‘pkey_set’:
   pkeys.c:22:12: error: void value not ignored as it ought to be
      22 |     return wrpkru(pkru);
         |            ^~~~~~~~~~~~
