POSIX er eit programkodelag mellom operativsystemet og brukarprogramma, som let brukarproggramma kalla opp POSIX-funksjonar, i staden for operativsystemspesifikke funksjonar. Dette gjer at eit brukarprogram kan nyttast på fleire ulike operativsystem, ved å rekompilera det. POSIX vart utvikla for <a href="/wiki/UNIX" class="mw-redirect" title="UNIX">UNIX</a>, men finst òg for fleire andre operativsystem. </p> <div class="mw-heading mw-heading2"><h2
