or_eq operator
| or_eq operator | Bitwise or assignment operator |
assignment-expr := logical-or-expr "|=" assignment-expr | logical-or-expr or_eq assignment-expr |
The or_eq operator is an assignment operator that performs bitwise inclusive or. It is equivalent to logical-or-expr = logical-or-expr | assignment-expr except that logical-or-expr is evaluated only once.
The keyword or_eq is interchangeable with the |= token.
Example
unsigned bitmask = 0xF0F0; bitmask |= 0x0102; // bitmask becomes 0xF1F2.
