InterlockedAndAcquire function

Performs an atomic AND operation on the specified LONG values. The operation is performed with acquire memory ordering semantics.

Syntax


LONG __cdecl InterlockedAndAcquire(
  _Inout_  LONG volatile *Destination,
  _In_     LONG Value
);

Parameters

Destination [in, out]

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

Value [in]

The second operand.

Return value

The function returns the original value of the Destination parameter.

Remarks

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 is implemented using a compiler intrinsic where possible. For more information, see the WinBase.h header file and _InterlockedAnd_acq.

This function is supported only on Itanium-based systems.

Note  This function is supported on Windows RT-based systems.

Note  Windows 8 does not support Itanium-based systems.
