Service_MessageFileClosed

(Service &5E)
Entry
R0 0 (not sure if actually required)
R1 94 (&5E)
Exit
R0 Preserved to pass on (do not claim)
R1 Preserved to pass on (do not claim)

Use

This service is issued by MessageTrans? to warn that all files have been closed.

Notes

This service call must not be claimed.

It is only needed by applications which use direct pointers into message files – they must re-open message files with MessageTrans_OpenFile? and recache pointers.

If applications are using direct pointers (e.g. indirected icons) with MessageTrans_MakeMenus? then they will need to close menus and re-make them if this service is issued.

Use Wimp_GetMenuState to check whether your own application’s menu is open – close it if it is.
