'--------------------
include "Util_FileDirectory.incl"

local fn Foo( f as ^FSRef )
'~'1
fn FD_ApplicationDirectoryGetFSRef( #f ) 
// '#' above means pass the value of f, not its address; f is already a pointer
end fn


dim as FSRef    ref
fn Foo( @ref ) 
// '@' above means 'pass the address of ref'.
// It is not actually needed in this case, because FBtoC
// automatically supplies it when the variable is a record.

'...do something with ref...
