--  The original idea of this package was to be an ASIS analog of the GNAT
--  Osint package and to contain the low-level routines needed by different
--  components of the ASIS implementation. But its current version contains a
--  very few routines, so probably we should merge this package with some
--  other ASIS implementation utility package.

with GNAT.OS_Lib; use GNAT.OS_Lib;
with Types;       use Types;

package A4G.A_Osint is

   function Normalize_Directory_Name
     (Directory : String)
      return String;
   --  Verify and normalize a directory name. If directory name is invalid,
   --  this will return an empty string (not implemented for now -  all the
   --  checks should be made by a caller). Otherwise it will insure a
   --  trailing directory separator and make other normalizations.

   function Get_Max_File_Name_Length return Int;
   --  yields the maximum file name length for system. Returns Int'Last,
   --  if the system does not limit the maximum file name length.

   procedure Free_Argument_List (List : in out Argument_List_Access);
   --  if List is not null, frees the memory occupied by its content

end A4G.A_Osint;
