6 Extensions to the C++ Language
********************************
The GNU compiler provides these extensions to the C++ language (and you
can also use most of the C language extensions in your C++ programs).
If you want to write code that checks whether these features are
available, you can test for the GNU compiler the same way as for C
programs: check for a predefined macro `__GNUC__'. You can also use
`__GNUG__' to test specifically for GNU C++ (*note Predefined Macros:
(cpp)Common Predefined Macros.).
* Menu:
* Volatiles:: What constitutes an access to a volatile object.
* Restricted Pointers:: C99 restricted pointers and references.
* Vague Linkage:: Where G++ puts inlines, vtables and such.
* C++ Interface:: You can use a single C++ header file for both
declarations and definitions.
* Template Instantiation:: Methods for ensuring that exactly one copy of
each needed template instantiation is emitted.
* Bound member functions:: You can extract a function pointer to the
method denoted by a `->*' or `.*' expression.
* C++ Attributes:: Variable, function, and type attributes for C++ only.
* Strong Using:: Strong using-directives for namespace composition.
* Java Exceptions:: Tweaking exception handling to work with Java.
* Deprecated Features:: Things will disappear from g++.
* Backwards Compatibility:: Compatibilities with earlier definitions of C++. |
