This pull request affects documentation only, and the contents seems to have been well-thought-out.
I suggest merging.

I don't understand. Why are you putting doc/Inline/C/Cookbook.pm into ./Cookbook.swim? The CONTRIBUTING file is a generated file for CPAN. It doesn't belong in the repo.

Please read and comprehend the About file and try again.

@ingydotnet
The content was put into a .swim file based on the recommendations of @mohawk2 and @daoswald here:
#56

The CONTRIBUTING file was also a recommendation by @daoswald ; while CONTRIBUTING may be automatically created by dzilla, this is not the case with the EU::MM projects I've worked on, and even GitHub's own docs talk about manually created this file:
https://help.github.com/articles/setting-guidelines-for-repository-contributors/#adding-a-contributing-file

We've all been trying our best to help @rongrw do the right thing, but since it does not meet with your approval, then it seems like you should provide some official guidance for @rongrw by clearly stating where do you want him to put the new content???

Hi @ingydotnet , @wbraswell ,
Yes, I didn't place the Cookbook.swim into the correct directory. This was certainly not intentional and I do apologise for that. Unfortunately I'm still in the process of learning the github web interface.

I would like to see the new recipe make its way into the C-Cookbook because I find this doc to be such an excellent learning tool with really interesting examples. To that end, if I could be given some further advice to get the changes approved, I'll do that.

Thank you for guiding me thus far, and I do realise that you are all very busy.

@rongrw, your contribution looks fine, but why on earth would you copy
./doc/Inline/C/Cookbook.swim to ./Cookbook.swim?

I don't have a CONTRIBUTING file in any of my repos, and I'm not going to add
one here. There's a CONTRIBUTING file in the CPAN dist.

Please change doc/Inline/C/Cookbook.swim in place and get rid of the
CONTRIBUTING file.

I fixed/applied your PR myself. Thanks.

I'd vote for a CONTRIBUTING file in the repo too, because people are working with the repo and not the CPAN dist, when they want to contribute. Also, github has support for it.
