 | Hello,
I have a question to this dce rpc function:
If a fully reseolved and connected (is_server_listening successfully called)
binding handle is copied, does then the destination binding handle also
'resuse' the physical IP connection or is there a new connection etablished
at the time of the first rpc?
The other question concerns multiple thread sharing the same (uncopied)
binding handle:
Is threadsafeness garanteed by RPC runtime or does the application have to
perform synchronisation? Is it in particularly made sure by rpc runtime,
that each thread receives the result for the request it made,even if another
threads makes a request at the same time with the same binding handle?
I am pretty sure, that the application does not have to care about
synchronization in this case, but this part of the DCE documentation made me
unsure:
rpc_binding_copy(3rpc)
"If you want the changes made to binding information by one thread to
affect the binding information used by other threads, your program must
share a single binding handle across the threads. In this case the
application controls binding handle concurrency."
best regards
Jakob
