In Jon’s 2023 article he showed a different attribute name and the count member name in quotes inside the attribute:

__attribute__((element_count(“count”)))

The online GCC and Clang documentation only mention counted_by and no sign of the quotes, so did the compilers agree on a better name while implementing this?

This extract of the article will likely answer your question:

#if __has_attribute(__counted_by__)
# define __counted_by(member) __attribute__((__counted_by__(member)))
#else
# define __counted_by(member)
#endif
