If they are defined, and your compiler isn't complaining then your compiler is seriously broken. >I think that is function overloaded. I'm I missing something? fcntl() is varadic, and it (at runtime) determines what (if any) the third arguement is from the second argument. If that doesn't appear to make sense, think of printf() and how it might determine the 2nd, 3rd etc. parameters. (And no, there isn't a definition of printf with every permutation of parameters in stdio.h .) -- PJH Quantum materiae materietur marmota monax si marmota monax materiam possit materiari?
