* @file
|
|
* @author Ruby developers <ruby-core@ruby-lang.org>
|
|
* @copyright This file is a part of the programming language Ruby.
|
|
* Permission is hereby granted, to either redistribute and/or
|
|
* modify this file, provided that the conditions mentioned in the
|
|
* file COPYING are met. Consult the file for details.
|
|
* @warning Symbols prefixed with either `RUBY3` or `ruby3` are
|
|
* implementation details. Don't take them as canon. They could
|
|
* rapidly appear then vanish. The name (path) of this header file
|
|
* is also an implementation detail. Do not expect it to persist
|
|
* at the place it is now. Developers are free to move it anywhere
|
|
* anytime at will.
|
|
* @note To ruby-core: remember that this header can be possibly
|
|
* recursively included from extension libraries written in C++.
|
|
* Do not expect for instance `__VA_ARGS__` is always available.
|
|
* We assume C99 for ruby itself but we don't assume languages of
|
|
* extension libraries. They could be written in C++98.
|
|
* @brief Various attribute-related macros.
|
|
*
|
|
* ### Q&A ###
|
|
*
|
|
* - Q: Why are the macros defined in this header file so inconsistent in
|
|
* style?
|
|
*
|
|
* - A: Don't know. Don't blame me. Backward compatibility is the key here.
|
|
* I'm just preserving what they have been.
