|
* @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 C-function backended Ruby-global variables.
