Is there any way that I could ignore some threads created by my application?

[Songyan Tang CN]

Hi all,

I static link DynamoRIO and use like this:

dr_client_main(...) {

 ...

} 

my_app_main() {

dr_app_setup();

// fork some threads here

// what I want is:

// for (auto thread : threads) {

// dr_ignore_thread(thread.id);

// }

// then when I call dr_app_start, these threads will not be captured by DynamoRIO

dr_app_start();

dr_app_stop();

dr_app_cleanup();

}

Please take a look at the function should_trace_thread_cb:

https://github.com/DynamoRIO/dynamorio/blob/0481c488b6adfe00307a12e71d59cf555a491dcb/clients/drcachesim/tests/burst_threadfilter.cpp#L112

If you know the thread IDs you want to ignore, you could use dr_get_thread_id.
