Re: this cast to const char*

Furthermore, using this memory layout enables array classes in the same
library to simply cast from CString* to const char** by a reinterpret
cast, which would necessarily cause an allocation otherwise.

So I would not bet that the implementation is done due to the printf
compatibility. This is most likely a spin off.

Makes sense.

The visual compiler painfully lacks similar analiser as gcc's
__attribute__(format) that checks the types and format string
components, my usual tech s to use format helpers consistently. I.e:

printf("int:%d, long: %ld, str: %s", f_d(i), f_ld(lo), f_s(str));

Well, C++ and printf...

It was just example. With MFC you certainly use CString::Format. That is IME
superior to most alternatives in most cases I worked with. And the above
trick covers the practical problems. (Certainly I'd wish to have gcc-like
compiler support...)

There is still no reasonable replacement in the standard. One must be
stoned to use the iostream output operators, because besides being type
safe they create completely unreadable code, at least if you use different
formatting (like hex and decimal) concurrently.

Yeah. :(
