Is there any way to detect if a certain code instruction in memory has been executed? And if it has been executed, I want to run one of my own functions in my program. Someone explained to me that SetUnhandledExceptionFilter in the Win32 API could be used to detect any changes made to memory, but he wasn't sure if it could be used to detect execution of certain part of memory. And I'm also not too sure how to use that function anyways, as I can't seem to find too many examples of its use.

So my question is, can I detect when an assembly code instruction in memory has been executed using that function or perhaps some other way entirely?

It ocurred to me that this somehow must be possible, considering debuggers are able to set breakpoints at certain points in memory. I just am not sure how to go about coding that sort of thing. All I would need to do is sort of set up a breakpoint at a memory location and execute my code instead of stopping execution of the program entirely.

Any help with this would be GREATLY appreciated.
