[Dpcl-user] Question regarding breakpoints...

[Philip M. <mu...@cs...>]

I'd like to be able to use DPCL like Dyninst to set a break
point in my code. SIGSTOP appears to be ignored when I send
it to an application under DPCL's control, but SIGTRAP is not.
However, AIS_main_loop() doesn't return when the process is stopped.

Any suggestions for how I should implement a 'stop at' probe?

With dyninst there is a probe expression for a break point. Basically,
this amounts to calling a function in Dyninst's run time library. There does
not appear to be such a symbol in dpcl however. My only other option would
be
to simplement a probemodule that just did raise(SIGSTOP).

Thanks for any help,

Phil
