You can't write a malloc routine in standard C which might be part of

What you *can* do though is statically allocate a memory buffer, then
allocate out of that with your own "malloc".
True, as long as you call is something other than malloc ;-)
It all depends on what the OP actually wants to achieve.
Wouldn't interpositioning allow you to define a default global symbol "malloc" that would essentially overwrite the Standard one?
Not, mind you, something I recommend, but isn't one of the hallmarks of C that one can do this without constraint, making all code (including any external libs that are linked in later) use the non-standard function?
