I have been thinking about the copyover idea and how it might be done. Please correct me if I am wrong in the following statements.
Allocated memory will never be freed as long as a process is using it. In this example, there will be two processes:
Process A is the old instance of the mud server. As soon as a privledged user types copyover, connected client information, active quest info, mob data, and similar information could be copied to a file. During this period, everything is frozen until process B - the new instance of the mud server - is initiated with the command line parameter "copyover". Process B could then reinstate the saved data and process A could close.
I am assuming the sockets will still remain in tact as long as the closesocket() function is never called in process A.
Since I am working with classes, I could save the memory addresses of clients to a file. This would be worthwhile if there was a way to retrieve a pointer variable in process B that points to these memory locations. Is there a way to do this in process B? If not, would the previous idea work? Is there a better way to perform a copyover? Thanks in advance for any help you can provide regarding this issue.
