Deze wijziging voorkomt onvoorspelbaar gedrag wanneer pointermanipulaties leiden tot een overflow van het type ptrdiff_t;\n<li class=\"l\"> De in POSIX voorgestelde functies pthread_cond_clockwait, pthread_mutex_clocklock zijn toegevoegd,<br \/>\n  pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock en sem_clockwait, vergelijkbaar met de &#171;timed&#187; equivalenten, maar met een extra parameter clockid_t voor het selecteren van de timer;<\/p>\n<li class=\"l\"> De coderingsgegevens, informatie over lettertypen en transliteratietabellen zijn bijgewerkt ter ondersteuning van specificatie Unicode 12.1.0;\n<li class=\"l\"> In de librt-bibliotheek worden de functies clock_gettime, clock_getres, clock_settime, clock_getcpuclockid en clock_nanosleep niet meer aangeboden voor nieuwe applicaties, in plaats daarvan worden automatisch de definities in libc gebruikt;\n<li class=\"l\"> De optie &#171;inet6&#187; is uit \/etc\/resolv.conf verwijderd. Verouderde vlaggen RES_USE_INET6, RES_INSECURE1 en RES_INSECURE2 zijn uit resolv.h verwijderd;\n<li class=\"l\"> Bij het opgeven van de optie &#171;&#8212;enable-bind-now&#187; worden de op te zetten programma's nu gelinkt met behulp van de vlag BIND_NOW;\n<li class=\"l\"> De headers sys\/sysctl.h en de functie sysctl, specifiek voor Linux, zijn als verouderd gemarkeerd, in plaats daarvan dienen applicaties het pseudo-bestandssysteem \/proc te gebruiken;\n<li class=\"l\"> Voor de bouw van Glibc is nu GCC 6.2 of een nieuwere versie vereist (voor de bouw van applicaties kunnen alle compilers
