https://bugzilla.kernel.org/show_bug.cgi?id=53061 Summary: pthread_kill() should describe it may cause SEGV when target thread doesn't exist Product: Documentation Version: unspecified Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: man-pages AssignedTo: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx ReportedBy: kosaki.motohiro@xxxxxxxxxxxxxx Regression: No Now, pthrad_kill() man page have following explanation. http://man7.org/linux/man-pages/man3/pthread_kill.3.html >ERRORS > > EINVAL An invalid signal was specified. > > ESRCH No thread with the ID thread could be found. But it is misleading. Current implementation cause SEGV when no thread ID exist highly likely. As suggested Rich on libc-alpha (http://permalink.gmane.org/gmane.comp.lib.glibc.alpha/28919). it would be nice if the man page point to following POSIX sentence. POSIX XSH 2.9.2: "The lifetime of a thread ID ends after the thread terminates if it was created with the detachstate attribute set to PTHREAD_CREATE_DETACHED or if pthread_detach() or pthread_join() has been called for that thread. A conforming implementation is free to reuse a thread ID after its lifetime has ended. If an application attempts to use a thread ID whose lifetime has ended, the behavior is undefined." -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
