Increments (increases by one) the value of the specified 32-bit variable as an atomic operation. The operation is performed using release memory access semantics.
Syntax
LONG __cdecl InterlockedIncrementRelease( __inout LONG volatile *Addend );
Parameters
- Addend [in, out]
-
A pointer to the variable to be incremented.
Return value
The function returns the resulting incremented value.
Remarks
The variable pointed to by the Addend parameter must be aligned on a 32-bit boundary; otherwise, this function will behave unpredictably on multiprocessor x86 systems and any non-x86 systems. See _aligned_malloc.
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 _InterlockedIncrement_rel.
For processors that do not support release memory access semantics, this function is defined as a call to the InterlockedIncrement function. For more information, see WinBase.h.
