InterlockedAnd function (winnt.h)

Performs an atomic AND operation on the specified LONG values.

LONG InterlockedAnd(
  [in, out] LONG volatile *Destination,
  [in]      LONG          Value
);

[in, out] Destination

A pointer to the first operand. This value will be replaced with the result of the operation.

[in] Value

The second operand.

The function returns the original value of the Destination parameter.

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.

For the Intel Itanium-based systems and x64 architectures, this function is implemented using the compiler intrinsic. For the x86 architecture, use the _InterlockedAnd compiler intrinsic directly.

This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.

Itanium-based systems:  For performance-critical applications, use InterlockedAndAcquire or InterlockedAndRelease instead.
