|
|
|
|
|
* TCP based RPC supports 'batched calls'.
|
|
|
|
|
* A sequence of calls may be batched-up in a send buffer. The rpc call
|
|
|
|
|
* return immediately to the client even though the call was not necessarily
|
|
|
|
|
* sent. The batching occurs if the results' xdr routine is NULL (0) AND
|
|
|
|
|
* the rpc timeout value is zero (see clnt.h, rpc).
|
|
|
|
|
*
|
|
|
|
|
* Clients should NOT casually batch calls that in fact return results; that is,
|
|
|
|
|
* the server side should be aware that a call is batched and not produce any
|
|
|
|
|
* return message. Batched calls that produce many result messages can
|
|
|
|
|
* deadlock (netlock) the client and the server....
|
|
|
|
|
*
|
|
|
|
|
* Now go hang yourself.
