I would like to see if there is a way to breakpoint if any function from a specific is called.

Thanks!

Well, this may be a specific case of a long trace so I guess this may not be possible...

If someone comes with any ideas, they are welcome.

hook all entry points of the functions in the dll. in the hook call a common function that just does nop and ret, and place a breakpoint on the nop
that way every function call will cause a break. you just have to step out of the hook, or inspect the stack, to see what the original function was

software breakpoints might work too

Thanks Dark Byte.

Let's say you have a quite long dll, how can you get all entry points with a script?

Thanks

EDIT: I figured out that maybe doing this automated won't be possible as entry points will have different looks.

you could automate it, but currently ce doesn't have a function to return a list of exports from the dll, only a per address querry. So you'd have to write a pe inspector in lua yourself

and then add in a check to see if the export is a function, or an variable (e. g check the first bytes for common function header code)


---
an alternate method would be to manually create a list of dll functions and break those (ce can use symbolnames and exportnames for breakpoints)
