Tests the specified bit of the specified LONG value and complements it. The operation is atomic.
FORCEINLINE BOOLEAN FORCEINLINE InterlockedBitTestAndComplement( _Inout_ LONG volatile *Base, _In_ LONG Bit );
Base [in, out]
A pointer to a variable.
The bit position to be tested.
The value of the specified bit.
The interlocked functions provide a simple mechanism for synchronizing access to a variable that is shared by multiple threads. This function is atomic with respect to calls to other interlocked functions.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
