warning C28112: A variable which is accessed via an Interlocked function must always be accessed via an Interlocked function

See line number: It is not always safe to access a variable which is accessed via the Interlocked* family of functions in any other way.

A variable that is accessed by using the Interlocked executive support routines, such as InterlockedCompareExchangeAcquire, is later accessed by using a different method.Although certain ordinary assignments, accesses, and comparisons to variables that are used by the Interlocked* routines can be safely accessed by using a different method, the risk is great enough to justify examining each instance.

Example

The following code example generates this warning:

inter_var --;  
...  
InterlockedIncrement(&inter_var);

The following code example avoids this warning:

InterlockedDecrement(&inter_var);  
...  
InterlockedIncrement(&inter_var);
