Warning: Symbols prefixed with either RBIMPL or rbimpl 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.

Q&A

Q: Why all the macros defined in this file are function-like macros?

A: Sigh. This is because of Doxygen. Its SKIP_FUNCTION_MACROS = YES configuration setting requests us that if we want it to ignore these macros, then we have to do two things: (1) let them be defined as function-like macros, and (2) place them separately in their own line, like below:

// NG -- foo's type  considered something like `unsigned int`.
RBIMPL_WARNING_PUSH
int foo(void);
RBIMPL_WARNING_POP
 
// OK -- the macros are ignored by Doxygen.
RBIMPL_WARNING_PUSH()
int foo(void);
RBIMPL_WARNING_POP()
