NAME: GetSelItem
SYNOPSIS: Gets the currently selected item from the File Manager Extensions.
ENTRY: hwnd - Handle passed by File Manager for FMX uses pnlsSelItem - pointer to string to receive the selection fGetDirOnly - Indicates if a file is selected, the file should be stripped thus only the files parent dir is returned pfIsFile - Set to TRUE if the selection is a file
EXIT:
RETURNS: NERR_Success if successful, error code otherwise
NOTES:
HISTORY: Johnl 21-Jan-1992 Moved from share stuff

NAME: FMX
SYNOPSIS: Communicates with File Man
INTERFACE: FMX - Constructor QueryFocus - Returns where focus is QuerySelCount - Returns number of selected items QuerySelection - Returns a selected item, has a flag that defaults to converting the path from OEM to ANSI. QueryDriveInfo - Returns drive info from the currently active window Refresh - Causes File Man to refresh ReloadExtensions - Causes File Man to reload all FM extensions
PARENT:
CAVEATS: This is, admittedly, a primitive interface.
NOTES: FMX calls are only guaranteed to work during calls out to FMExtensionProc. It would be nice if these classes could attempt to enforce this. But then, on the other hand, perhaps we'd still like to call in at some other time.
To get FM's hwnd, listen for the first FMExtensionProc message. It would be nice if that could be done automatically.
