◆ XAPIAN_CONST_FUNCTION
| #define XAPIAN_CONST_FUNCTION |
A function which does not examine any values except its arguments and has no effects except its return value.
This means the compiler can perform CSE (common subexpression elimination) on calls to such a function with the same arguments, and also completely eliminate calls to this function when the return value isn't used.

◆ XAPIAN_PURE_FUNCTION
| #define XAPIAN_PURE_FUNCTION |
