This correspondence is defined by the -- two subprograms defined here in the Fname package. -- For full rules of file naming, see GNAT User's Guide. Note that the -- naming rules are affected by the presence of Source_File_Name pragmas -- that have been previously processed. -- Note that the file name does *not* include the directory name. The -- management of directories is provided by Osint, and full file names -- are used only for error message purposes within GNAT itself. ----------------- -- Subprograms -- ----------------- type Expected_Unit_Type is (Expect_Body, Expect_Spec, Unknown); -- Return value from Get_Expected_Unit_Type function Get_Expected_Unit_Type (Fname : File_Name_Type) return Expected_Unit_Type; -- If possible, determine whether the given file name corresponds to a unit -- that is a spec or body (e.g. by examining the extension). If this cannot -- be determined with the file naming conventions in use, then the returned -- value is set to Unknown. function Is_Predefined_File_Name (Fname : File_Name_Type; Renamings_Included : Boolean := True) return Boolean; -- This function determines if the given file name (which must be a simple -- file name with no directory information) is the file name for one of -- the predefined library units. On return, Name_Buffer contains the -- file name. The Renamings_Included parameter indicates whether annex -- J renamings such as Text_IO are to be considered as predefined. If -- Renamings_Included is True, then Text_IO will return True, otherwise -- only children of Ada, Interfaces and System return True. function Is_Internal_File_Name (Fname : File_Name_Type; Renamings_Included : Boolean := True) return Boolean; -- Similar to Is_Predefined_File_Name.
