Description

The function server-in-use-p returns true when the COM server is in use, which means one or more of the following:

1. There are live objects other than the class factories.
2. Any of the class factories has more than one reference.
3. The server is locked by a client call to the COM method IClassFactory::LockServer.

The function server-can-exit-p returns true if the server can exit, which means that the server is not in use (that is, (not (server-in-use-p)) returns t), and also that there are no other "working processes", which means that all other processes except the one that calls server-can-exit-p are "Internal servers" (see mp:process-run-function).

The main purpose of server-can-exit-p is to be the exit-function for automation-server-top-loop, either as the default or called from a supplied exit-function.
