Tests the specified bit of the specified LONG64 value and complements it. The operation is atomic.
BOOLEAN __cdecl InterlockedBitTestAndComplement64( _Inout_ LONG64 volatile *Base, _In_ LONG64 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.
Note This function is only supported as inline code, it does not correspond to an intrinsic function.
