Problem with fcntl

Hi all,

I've a little problem with UDP socket (based on Interniche Stack).

I want set the option "O_NONBLOCK" in my socket, but when

I retrieve the socket options from socket with

flags =fcntl(sock,F_GETFL);

flags is "-1" (not correct) :cool: but the enviroment variable errno is "0".:eek:

Non error occurred during socket creation.

any suggestion? :confused:

Thankx
