InterlockedIncrement16Release function

Article
2018-03-28

Increments (increases by one) the value of the specified 16-bit variable as an atomic operation. The operation is performed using release memory ordering semantics.

Syntax

short __cdecl InterlockedIncrement16Release(
  _Inout_ short 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 16-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 _InterlockedIncrement16_rel.

For processors that do not support release memory ordering semantics, this function is defined as a call to the InterlockedIncrement function. For more information, see WinBase.h.

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

Requirements

Minimum supported client	Windows 8 [desktop apps only]
Minimum supported server	Windows Server 2012 [desktop apps only]
Header	Winnt.h (include Windows.h)
