Compaq TP DESKTOP CONNECTOR AAPVNFGTE - Manual (Page 76)

acmsdi_check_version
Return Status
The TP Desktop Connector service checks the status value returned and
expects a valid OpenVMS status. If a failure status is returned, the TP
Desktop Connector run-time system terminates the ENABLE request.
If the version-checking routine determines that software is not synchronized, it
does one of the following:
• Returns an OpenVMS failure status that cancels the ENABLE request.
• Sets a flag that causes the acmsdi_enable routine to terminate with a
failure status.
