Best if you don't do it at all.  It would make your program limited to
a single version of a single programming toolchain, as you'ld have to
look into details considered private to the implementation of
malloc().

If you need that value, remember it in your program.  Anyway: what
would you need the previous size of the array for, in a realloc()
call? You're just modifying that size anyway, so why bother what it
was before?
