MBS( "Plugin.PrepareForUpdate" )




Returns OK or error.


Prepares plugin for an update.
MBS Plugin prevents FileMaker from unloading itself to avoid crashes with Cocoa runtime system.
e.g. one plugin loads, registers a class. Then it may get deactivated and unloads. Later a newer plugin in a different version loads, and tries to use the class registered before. Since the first plugin is unload, all pointers are invalid and the application crashes.
This function disables this feature, so a newer plugin may load.
