      [edit]Parameters

      desired - value to assign

      [edit]Return value

      As described above.

      [edit]Notes

      Unlike most assignment operators, the assignment operator foratomic_ref does not return a reference to its left-hand argument. It returns a copy of the stored value instead.

      [edit]Defect reports

      The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
