Hi,

setpgid(2) and exit(3) use the term 'orphaned process group', but they don't define it.

And if I am not missing it, the term is not defined in a referenced man page, either.

Suggested fix: add the defintion of 'orphaned process group' to the 'right' place(s) (man-page).

Best regards
Georg Sauthoff

Thanks for your report. I made the following patches for man-pages- 3.23.

Cheers,
