I agree that there is a bit of confusion in the wording of the page. I changed this paragraph to read: If retval is not NULL, then pthread_join() copies the exit status of the target thread (i.e., the value that the target thread sup‐ plied to pthread_exit(3)) into the location pointed to by retval. If the target thread was canceled, then PTHREAD_CANCELED is placed in the location pointed to by retval. Okay?
