Speculation is fine, but this sub-forum is a technical one for discussing programming.

If you're not going to "do" anything on your part, then the question is more opinions and academic. If so, the Non-nix/general forum may be better for that type of discussion.

What are you writing about? It doesn't make sense. It's like you're making judgement about something you haven't even read.

I sought a C routine (see title), and the only constructive advice is Ser Olmy stating echo commands are readable in compiled C.

In addition to SerOlmy's poets, see #'s 2,3,5,7,13,14, ...

What I'm talking about is that there are libraries in C which you can use.

We're not here to look things up for you.

But I did check github before my first response. Plenty of libraries or code projects, and it has been suggested many times that what you wish to do seems very customized, so you should try coding a solution yourself.

Happy to help you along with code, but you would need to write some to show that you really aren't wasting anyone's time, or illustrate a different way you've decided to follow to achieve your desired result. People have suggested off-the-shelf solutions as well as specific libraries.

@JASlinux - Please review the Site FAQ for guidance in asking well formed questions and general forum usage. Especially visit the link from that page, How to Ask Questions the Smart Way for discussion of things to consider when asking others for help.

Please also remember that this forum is frequented by members of all ages and sensibilities, please refrain from inappropriate comments.

You have stated your requirements several times in different ways, and received several helpful suggestions. Repeating those requirements is not really helpful, and as others have said, it would be most helpful if you could attempt to implement a solution based on one or more of those suggestions, or an idea of your own, then show us where you are having trouble so others can offer specific help. Otherwise the thread ultimately becomes a request for others to provide a complete solution and this is not the appropriate place for that.

Good luck!

...or just input the KEY YOU SEND THEM, as you're saying you want....
So again...they don't 'install anything'....except YOUR program, right??
Ah, so your 'solution' is to have them install the pkzip utility...after you said you didn't want them to install anything, just like PGP shouldn't be used, because they'll have to have IT, right???

You're just not making logical sense.
