Hello! I found that lua engine in CE is very handy when I try to automate my debugging.
Recently I play with a muti-thread application but with a problem. I set a breakpoint on an address that several threads will run through.
debugger_onBreakpoint() get called but I cannot find a way to distinguish between threads (I want to peform some operations depending on thread id).
I found that thread id show on the top of window while I'm debugging manually( as shown in the figure 0).So I think that there should be a lua function like "getCurrentThreadId". I dig through docs and googles but nothing found.
I get stucked and please help me out if any one has any solution. btw It's my first post ever.please be kind if I'm asking a foolish question.

there is currently no option for that, but i'll look into adding it.

an alternate way to distinguish between threads is look at the esp/rsp value during breakpoint as every thread will start their stack at a different position

Thanks for help. I wrote a plugin in the end. ce-plugin-system is more powerful to suit my needs.
But I still failed to find some functions from exported functions. e.g.,I want to get the stacktrace when a debugEvent occurs. Do I need to implement that function myself(using winapi stackwalk,as I know)?
