ARENE_STD_INLINE_VARIABLES

#define ARENE_STD_INLINE_VARIABLES

A platform support query for testing if __cpp_inline_variables is defined.

Usage:

#if ARENE_IS_ON(ARENE_STD_INLINE_VARIABLES)

The value of this query is determined as follows, in order of precedence:

1. If ARENE_STD_INLINE_VARIABLES has been explicitly defined via a -D flag to the compiler or similar:
   • ARENE_ON if it is truthy
   • ARENE_OFF if it is not truthy.

1. If __cpp_inline_variables is defined and its value is >=201606, it is ARENE_ON_BY_DEFAULT

1. Otherwise, it is ARENE_OFF_BY_DEFAULT
