I can't find Stevens ourhdr.h

[Peter Percival]

W. Richard Stevens' /Advanced programming in the Unix environment/
features a file ourhdr.h. I have downloaded the source code for the
book from http://www.kohala.com/start/apue.tar.Z. There are a number of
files called ourhdr.h but they all seem to be empty.

I downloaded and expanded apue.tar.Z on a Windows 10 computer using
WinZip with a view to transferring them, via a USB stick, to a Raspberry Pi.

You should extract the files on Unix/Raspbian, as they understand links.
"zcat apue.tar.Z |tar tvf - |grep link\ to" gives:
