Subj : Re: pthread_mutex_lock throws an exception on receiving signal 15 To : comp.programming.threads From : pankaj-startup Date : Tue Oct 04 2005 01:12 pm Few more observations: I called exit(0) on recieving signal 15, and process terminated gracefully without dumping core. If this is the case, why do people want to cancel threads before exiting? It is observed on aix 5.1 .
