How would I use a C function from LLVM IR?

What would be the correct way of writing a C function which then I link to my llvm IR program.

This is how I currently compile my program:

clang -c out.ll -o out.o
clang out.o -o out

This is roughly my C function:

void __write(char *s)

which I declare in llvm like this:

declare void @__write(i8*)

I don’t really know how to link these two as I am quite the begginer with Clang and LLVM.

I’ve searched for this topic plenty but found no clear answers so far.
