Question Check if another process writes to a specific address in memory

[geordie0511]

I'm using the 'ReadProcessMemory' function (kernel32.dll) to check if a specific memory area was changed (array of bytes) by another process. In this case it's no problem.

Sometimes the other process overwrites the memory area with the same array of bytes, so it looks like nothing has changed.

I need to know WHEN the other process is actually accessing (for writing to it) a memory area.

Is that possible ?
