I'm not really sure I see who could benefit from something like that. If the coder already knows the basics of C and you want to bring them up to speed on the details they'll have to know to work on your library then I don't think you'll need to explain that "A function is a basic unit of execution" or that "Memory to a machine is just a big “spreadsheet” of numbers" for instance. This is clearly meant for complete novices, but at the same time it introduces too many concepts at once to work as a tutorial to learn C from scratch. Instead focus on how your libraries are architectured, how the pieces fit together, the rationale for why things are this way etc... See for instance "linux device drivers"[1] as an example of what I'm talking about. I know C and this "primer" doesn't give me anything valuable if I actually wanted to hack on their libraries. On the other hand if the coder really doesn't know what a function or a struct is then it's probably a better idea to tell them to follow some actual C tutorial and come back when they're done because this particular text will probably overwhelm and confuse them, not actually give them the skills necessary to actually contribute decent C code anyway.
