26 -- This package contains data and functions used to determine if a given
27 -- unit is an internal unit intended only for use by the implementation
28 -- and which should not be directly WITH'ed by user code. It also checks
29 -- for Ada 05 units that should only be WITH'ed in Ada 05 mode.
31 with Types
; use Types
;
37 -- Unit from predefined library intended to be used only by the
38 -- compiler generated code, or from the implementation of the run time.
39 -- Use of such a unit generates a warning unless the client is compiled
40 -- with the -gnatg switch. If we are being super strict, this should be
41 -- an error for the case of Ada units, but that seems over strenuous.
44 -- This is not a predefined unit, so no checks are needed
47 -- This unit is defined in the Ada 95 RM, and can be freely with'ed
48 -- in both Ada 95 mode and Ada 05 mode. Note that in Ada 83 mode, no
49 -- child units are allowed, so you can't even name such a unit.
52 -- This unit is defined in the Ada 05 RM. Withing this unit from a
53 -- Ada 95 mode program will generate a warning (again, strictly speaking
54 -- this should be an error, but that seems over-strenuous).
56 function Get_Kind_Of_Unit
(U
: Unit_Number_Type
) return Kind_Of_Unit
;
57 -- Given the unit number of a unit, this function determines the type
58 -- of the unit, as defined above.
60 function Is_Known_Unit
(Nam
: Node_Id
) return Boolean;
61 -- Nam is the possible name of a child unit, represented as a selected
62 -- component node. This function determines whether the name matches
63 -- one of the known library units, and if so, returns True. If the name
64 -- does not match any known library unit, False is returned.
