ConsoleImpl.h@ 4044

Last change on this file since 4044 was 4041, checked in by vboxsync, 17 years ago

Main: Shared Folders (#2130):

Solved folder name unicity problems by introducing scope precedence (transient, then permanent, then global).
Implemented VM process notification on permanent (machine) shared folder change.
