InterlockedAdd64

InterlockedAdd64 performs an atomic addition operation on the specified LONGLONG values.

Syntax

LONGLONG InterlockedAdd64(
        LONGLONG volatile *Addend,
        LONGLONG           Value
);

Parameters

Addend

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

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 _InterlockedAdd64.

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