If you just want to decide, based on the client IP address, whether to
accept or decline a connection request from the client, you can use the
gatekeeper interface inside omniORB. See the user guide for details.

On the otherhand, if your design requires you to determine the client IP
address inside the implementation of an operation, you can use the
gatekeeper interface to extract the client IP address from the socket
(using getpeername()), put the info into a per-thread storage and
extract
the value in your implementation. You either use the pthread "key" or
the
equivalent in Win32 thread API to access the per-thread storage. With
Win32, you must clean up the storage after use or there will be a memory
leak.
