Exit Status & Rückgabewert

Submitted by rac on 12 January, 2008 - 17:31.
  • Pthread kann joinable oder detached sein > Rückgabewert
  • pthread_join() nur für joinable Pthread möglich 
 int pthread_join( pthread_t th, void **thread_return);
  • Rückgabewert liefert entweder pthread_exit() oder die Funktion, welche pthread_create() ausführt
  • pthread_create() gibt (void *) zurück
    • evtl. Wert umwandeln (cast)
    • Achtung: den Wert PTHREAD_CANCELED nicht verwenden! Dieser ist per Def. weder eine gültige Adresse (Pointer!) noch NULL.
