I haven't hit a problem yet. That's not going to exercise all the possible buffer calculations--it probably doesn't perform any ACL operations, for example. I wonder if it would be possible to generate those buffer sizes directly from the .x files or something? > And besides, the RPC buffers are all a fixed size (2kiB), and much > larger than required already. The slack is "built in" to the buffer size. OK. Do we know of any calls or replies that are close to that limit? --b. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
