The xor_eq macro, which is part of [[c/iso646.h<iso646.h>#|iso646.h<iso646.h>]], is a convenient object-like macro name that expands to the ^= operator. The macro was added in Normative Addendum 1 in an effort to provide support for international character sets that might not have the ^ symbols.
Synopsis
#include <iso646.h>
#define xor_eq ^=
Description
The xor_eq object-like macro expands to the ^= operator.
Example
#include <iso646.h>
