I'm not sure what exactly you want to do, or what your question is, but
you can override every C library function with your own version. Just
link it in, and the linker won't use the code from the library. (That's
one of the advantages of a library-based implementation, as opposed to a
compiler-based implementation, if you remember this discussion a while
ago :)

However, you need to provide every function that's needed and that's in
one library source file. (Link modules are normally file-based.) That
is, if you want to substitute C library functions, you need to
substitute all functions that are in one C library source file. Which
typically are not many.

This works if the C compiler is ANSI C.
