If multiple, related, programs running on unix (Linux, Solaris etc.) refer to the same configuration file accessed via a TIniFile, is there any recommended "good practice" to ensure that they don't try to update it simultaneously?

In the case that I'm thinking of, I don't anticipate e.g. multiple logins trying to write setup information at the same time. The more risky case is if there are e.g. multiple daemons or apps trying to save state when a UPS signals imminent shutdown.
