Installation

Writers of MTMs need to inform the message server of the properties of the MTM by supplying a registration file. This is a compiled resource file, placed in \system\mtm\ (pre-v9.0) or \resource\messaging\mtm\ (from v9.0). The resource file should define the MTM's properties using the resource structures MTM_INFO_FILE, MTM_CAPABILITIES, and from v9.0, also MTM_SECURITY_CAPABILITY_SET.

To install an MTM that is not in ROM on to a target phone, you must take an additional step of calling the Message Server, through CMsvSession::InstallMtmGroup(), to notify it that a new MTM is available. When this is done, all running Message Server client processes are also notified that the new MTM is available. A program to do this would typically be run at the end of installation.

Uninstallation also requires a call to the Message Server. Running clients are then dynamically notified that the MTM is no longer available.
