How to add a function in C library ?

Answer 1

Try and get in touch with the C standards committees. Easiest way is to post on comp.lang.c (or is it comp.std.c?). Anyway, explain your superbly amazing function, writing the implementation code, and why it should be including the standard library.

Then debate over it, trying to survive the probes of a number of other brilliant minds. Try to keep everyone convinced that your function is the next best thing, for about a decade or whenever the next standard gets released. Then, there you go ;p

Oh wait, did you intend something else? Sorry, I'm not psychic, so you may have to say something more. More = more than one vague line.

Answer 2

It seems such as you prefer to apply a function that's in a library. you're able to try this with the aid of asserting a prototype of the function on your document, so as that the compiler knows the protocol used for that function. The linker might would desire to comprise the library document in the linking technique. Your substantial question, inspite of the shown fact that, seems to be asking the thank you to construct your own library. you may write purposes, yet not have a substantial function, and as a substitute of having the linker construct an executable, you prepare it to construct a library. Then different courses can get admission to those purposes in that library. the relatively instructions used to do those issues selection between compilers. you will possibly prefer to learn the ideas to your compiler/linker to comprehend the thank you to do it.

Do you mean how to properly program headers?
