How can you programmatically check to see if an address is static with WINAPI?

I know you can get a module or process' total memory size, but can't find a way to determine what the last static address is, or what the size of statically-allocated memory is for a given process or determine if a specific address is within static memory.

Obviously I could open CE and see if it is green, but I want to understand how to accomplish this. I thought there was a similar post on this forum but couldn't find this information anywhere on the web - kept finding answers on how to tell how much *YOUR* program is using, but not a 3rd party program at runtime Sad

This might work
Code:
        bool IsStatic(int Addy, string ProccessName)
        {
            System.Diagnostics.Process[] P = System.Diagnostics.Process.GetProcessesByName(ProccessName);
            if (P.Length == 0) return false;
            foreach (System.Diagnostics.ProcessModule M in P[0].Modules)
            {
                if (Addy >= M.BaseAddress.ToInt32() & Addy <= M.BaseAddress.ToInt32() + M.ModuleMemorySize)
                    return true;
            }
            return false;
        }


Loop the modules, if the address you're checking is between Base and Base+Size, its static

If you wish to return the module name and offset
Code:
        string RetStatic(int Addy, string ProccessName)
        {
            System.Diagnostics.Process[] P = System.Diagnostics.Process.GetProcessesByName(ProccessName);
            if (P.Length == 0) return Addy.ToString("X");
            foreach (System.Diagnostics.ProcessModule M in P[0].Modules)
            {
                if (Addy >= M.BaseAddress.ToInt32() & Addy <= M.BaseAddress.ToInt32() + M.ModuleMemorySize)
                    return M.ModuleName + "+" + (Addy - M.BaseAddress.ToInt32()).ToString("X");
            }
            return Addy.ToString("X");
        }
