Hi Ilia,

you may use such files provided by the C spec implementation, 
POSIX/UNIX or the core OS itself.  E.g. err.h API is not part of the C 
spec nor POSIX or UNIX but it's OK to use that as its implementation 
is part of Linux glibc.

We do not want you to use any existing tar implementation code or any 
other "helper" code you might find on github or provided by a fellow 
student, etc.

The objective is that you learn C by completing some non-trivial code.

So, in the code you put into your repository, there should be no code 
written by someone else.  By #including a system header, you are not 
putting the file/code into the repo.  If what you want to use is not 
in system (g)libc, you should not use that.  Also note that we require 
only one file, mytar.c, so that precludes adding any other (header) 
files to your project repo.

If unsure about specific use of something possibly outside of what I 
wrote above, please ask.

Regards,
Jan
