InterlockedAdd

InterlockedAdd performs an atomic addition operation on the specified LONG values.

Syntax

Copy

LONG InterlockedAdd(
    [in, out]  LONG volatile *Addend,
    [in]       LONG           Value
);

Parameters

[in, out] Addend

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

[in] Value

The second operand.

Return Value

The function returns the result of the operation.

Remarks

The interlocked functions provide a simple mechanism for synchronizing access to a variable shared by multiple threads. This function is atomic concerning 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 _InterlockedAdd.

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