Hi, All, I plan to use setsockopt() to set the socket buffer size to get better throughput for my omniORB testing work. To use setsockset(int socket, int level, int option_name, const void *option_value, size-t option_len), I have to know the socket number we are using for omniORB communication. How can I get the socket number? Thanks in advance for your help! Sincerely, Youzhong
