The purpose of this call is to unregister/remove an image filing system from the list maintained by FileSwitch.
It calls the image filing system to close open files, flush buffers, and so on. You should use it in the finalise entry of an image filing system module.
Image filing systems must be removed on any type of finalisation call, and added on any kind of initialisation. The reason for this is that FileSwitch keeps pointers into the image filing system module code, which may be moved as a result of tidying the module area or other such operations.
Image filing systems can only be removed by passing the filing system’s filetype. Attempting to use the filing system number will result in an error being returned.
Modules must not complain about errors in filing system removal. Otherwise, it would be impossible to reinitialise the module after reinitialising the filing system manager.
