Restrict pointers?

[Frederick Gotham]

I did a search through the C++ Standard there, and couldn't find any
mention of "restrict" or "__restrict__". Firstly, could someone please
confirm whether "restrict" is mentioned in the C++ Standard?

A quick search of the web shows up a few pages which imply that C++ has a
"__restrict__" keyword... is there any truth to this?


Basically my question is:

Does C++ have restrict pointers?

No, only C99 has the keyword restrict, not C++, unless
provided as a compiler extension.

No, that is a C99 feature.

It would also be less useful in C++, where passing multiple pointers
to primitive types is less common. Parameters of different class types
are already known not to have an alias problem.
