Hi ,
 
I have a question? I want to have a server application which is listening on  UDP ,TCP and SCTP port(one to one style socket). Now if a message has arrived on the server application how will it determine that message has come on which socket fd ? Using getsockopt function  i could determine whether the message has come on UDP or TCP only. Also the ext_getsockopt function (present in socketapi-1.7.0)determines options only for SCTP.
 
For TCP and SCTP (one to one style socket) the socket type is SOCK_STREAM.
 
I would be thankful if there is some way to know on which fd message has arrived.
 
Thanks and regards
Rohit Agrawal
