Each katcp client connection keeps it state a handle/state structure (katcl_line) - so there shouldn't be global variables to be overwritten. This means where you use select() on multiple connections or only use a connection per thread you should be fine. However, access to individual data structures isn't locked - thus if you access the same data structure from multiple threads you will need to provide your own mutexes. [Personally I find that threads make reasoning about code quite a bit harder, and thus prefer to use select() or poll() for doing concurrent IO, even if the initial effort is a bit more] regards marc
