void	checkMacro (const Token &MacroNameTok, const MacroInfo *MI, const SourceManager &SourceMgr)
	Check Macros for style violations.

Detailed Description

Checks for usages of identifiers reserved for use by the implementation.

The C and C++ standards both reserve the following names for such use:

identifiers that begin with an underscore followed by an uppercase letter;
identifiers in the global namespace that begin with an underscore.

The C standard additionally reserves names beginning with a double underscore, while the C++ standard strengthens this to reserve names with a double underscore occurring anywhere.

For the user-facing documentation see: https://clang.llvm.org/extra/clang-tidy/checks/bugprone/reserved-identifier.html
