The Rendezvous Environment Before using Rendezvous communications, programs must open the Rendezvous environment. Opening the environment initializes crucial global resources. All communication and event operations depend on this step; the only operations that do not require it as a precondition are message operations. The open call creates a default event queue, an intra-process transport, an event driver, and other resources within the program. Closing the environment destroys these resources.
