Thanks Dan for the clarification. I think it might be worth mentioning in the doc that this function might create a thread. Would setting CURLOPT_RESOLVE result in curl_multi_perform never creating a new thread?
Also when I run multi-app.c in helgrind, I see: > ==339231== ---Thread-Announcement------------------------------------------ > ==339231== > ==339231== Thread #1 is the program's root thread > ==339231== > ==339231== ---------------------------------------------------------------- > ==339231== > ==339231== Thread #1: pthread_mutex_destroy with invalid argument > ==339231== at 0x483FC96: ???
