Something about Linking

[comp.lang.c++.moderated]

The MSVC CRT source code contains ::operator new function definition(I
can jump into it when debugging), so can I say there's a function
built into the crt library? If so, when I define my own ::operator new
function and use static link, when no ``function already defined in
*******" error?

This is somewhat implementation specific, but generally names defined
in your code are resolved first, and only later does the linker look
for names in libraries.

In this particular case, you will not get the entire library linked
in, just the functions (and operators) that you actually use.
