Determine if a memory location changes value

Determine if a memory location changes value

In Windows (both 32 and 64 bit), through program (C++) is it possible to
determine if a certain memory location has changed? I am trying to
extrapolate the concept that we see in Visual Studio where we can set data
break point.
Use Case: I have a pre allocated memory that I would like to keep a watch
and when ever it changes, I would like a trigger to get generated to take
a certain action asynchronously and subsequently continue execution.
