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