While implementing and debugging a server program you may temporarily want to communicate binding information to clients by using string bindings. This allows a server to establish a client/server relationship without registering endpoints in the local endpoint map or exporting binding information to a namespace.
The server can convert into a string each binding handle in the list obtained from the rpc_server_inq_bindings( ) call by calling rpc_binding_to_string_binding( ). The resulting string binding is always fully bound. The server then makes some or all of its string bindings available to clients somehow; for example, by placing the string bindings in a file to be read by clients or users or both.
