I've done that for libraries that a program doesn't normally need. But it doesn't make sense for a long-lived daemon. The work almost certainly needs doing at some point. The other problem is that it is hard to handle symbol versioning. So the function you get may not match the one the header file defined and you suffer the consequences. David
