I am a new NeXT user trying to write some programs using Mach primitives. I will probably have planty of questions in the near future; in fact I have some minor ones now. If there was a comp.os.mach I would post these there but this seems to be the best choice currently. Note I do not need to use the spiffy NextStep interface stuff (yet!), these initial questions deal with the Mach kernel. 1. In getting a simple server/client example to run we got a linker error message "undefined external _MsgError". From the docs I could find I believe that this function is supplied by me. I wrote an empty function to satisfy the linker. What kind of actions would I want to take in MsgError? 2. The application we have in mind will have a collection of servers receiving messages from a single client. Can we set it up so the client generates messages to the servers asynchronously and then requests results from the servers at the conclusion of the execution? The example we have (arithmetic server) blocks until the server's results are returned. I envision that we could have the servers reply immediately to incoming messages from the client. That's it for now. Am I hosed or what? Thanks for your attention. ---------------------------------------------------------------------- "Above opinions are my own, not my employer's" John Lindwall johnl@tw-rnd.SanDiego.NCR.COM
