How to tell if there is an active scm daemon running with current login on Linux

I am wrting a script to load a number of objects into the repository workspace. I don't want to place my login credentials in a script. But, I do want the script to be able to query if a login is present for the repository. I would prefer using an scm command to do this rather than using the system to check the processes.

Does lscm login return an error code if the login is already active. Or does it start another daemon.
