Hi all,

Simple question: is size_t in the std namespace or not?

18.1 and 5.3.3 do not appear to say anything about it being so; indeed,
18.1 seems to imply that it is not so. However, std::size_t is mentioned
elsewhere in the standard, and in several of the better textbooks.

Thanks,
Chris

Back up to 17.4.1.1:

All library entities except macros, operator new and operator delete are defined within the
namespace std or namespaces nested within namespace std.

17.4.1.1p2: "All library entities except macros, operater new and
operator delete are defined within the namespace std or namespaces
nested within namespace std."

I believe that typedefs such as size_t are entities within the meaning
of this paragraph.

See 17.4.1.2./4: "In the C++ Standard Library, however, the declarations
and definitions (except for names which are defined as macros in C) [in
the cname headers] are within namespace scope of the namespace std."

For those of us who don't have a copy of the C89 standard, does anyone
have a list of exactly which names are macros?

DId you look at Appendix C.2 of your C++ standard.  Tables 95 and 96
list them.  All of the C carry overs into C++ are listed (although
you'll need to go to the C standard to get the definintion of their
meanings.

A casual look at the the C89 spec looks like they got them all.
