How to set a data watch point for a particular memory address value?

[kailashg26]

Hello, I'm trying to set a hardware data watchpoint for a particular memory address value. I also downloaded the code and tried to execute it (successfully compiled and working). But can you give me an example of how to set a watchpoint on a particular memory address value. Like, can you give an example on set the watchpoint and trigger an exception.
The output I'm getting:
failed to set the breakpoint!
handled: 0
failed to disable the breakpoint!

Thanks again!

Are you running the program as root?

Can you also give an example on how to give a memory address value and trigger an exception ?
