warning C6316: Incorrect operator: tested expression is constant and non-zero. Use bitwise-and to determine whether bits are set
This warning indicates the use of bitwise-or (|) when bitwise-and (&) should have been used. Bitwise-or adds bits to the resulting expression, whereas bitwise-and selects only those bits in common between its two operators. Tests for flags must be performed with bitwise-and or a test of equality.
