Yup, dar, din ce am citit POSIX spune ca fcntl se foloseste pentru asta...<div class="Ih2E3d"><br><div> </div>Dragos Dumitru Sbīrlea<br><span style="color: rgb(91, 91, 91);">Facultatea de Automatica si Calculatoare</span>

<div><div style="font-family: times new roman,new york,times,serif; font-size: 14pt;">Ca sa fim chitibusari (sau iubitori de corectitudine) ar trebui mai intai sa luam flagurile curente (F_GETFL) pentru socket si apoi sa adaugam flagul O_NONBLOCK. :)
