The InterlockedIncrementAcquire routine uses acquire semantics to increment a caller-supplied variable.
- Addend [in, out]
A pointer to the variable to increment.
InterlockedIncrementAcquire returns the incremented value.
The InterlockedIncrementAcquire routine performs the same operation as InterlockedIncrement, except that the former guarantees only acquire semantics whereas the latter guarantees both acquire and release semantics. For more information about acquire and release semantics, see Acquire and Release Semantics.
On processors that do not support acquire-semantics operations, InterlockedIncrementAcquire is identical to InterlockedIncrement. On processors such as Intel Itanium-based processors, which do support these operations, InterlockedIncrementAcquire runs faster.
Interlocked operations cannot be used on non-cached memory.
