--  This package contains the low level, operating system routines used only

--  in the GNAT binder for command line processing and file input output.

package Osint.B is

   function More_Lib_Files return Boolean;

   --  Indicates whether more library information files remain to be processed.

   --  Returns False right away if no source files, or if all source files

   --  have been processed.

   function Next_Main_Lib_File return File_Name_Type;

   --  This function returns the name of the next library info file specified

   --  on the command line. It is an error to call Next_Main_Lib_File if no

   --  more library information files exist (i.e. Next_Main_Lib_File may be

   --  called only if a previous call to More_Lib_Files returned True). This

   --  name is the simple name, excluding any directory information.

   -- Binder Output --

   -------------------

   --  These routines are used by the binder to generate the C source file

   --  containing the binder output. The format of this file is described

   --  in the package Bindfmt.

   procedure Create_Binder_Output

     (Output_File_Name : String;

      Typ              : Character;

      Bfile            : out Name_Id);

   --  Creates the binder output file. Typ is one of

   --

   --    'c'   create output file for case of generating C

   --    'b'   create body file for case of generating Ada

   --    's'   create spec file for case of generating Ada

   --

   --  If Output_File_Name is null, then a default name is used based on

   --  the name of the most recently accessed main source file name. If

   --  Output_File_Name is non-null then it is the full path name of the

   --  file to be output (in the case of Ada, it must have an extension

   --  of adb, and the spec file is created by changing the last character

   --  from b to s. On return, Bfile also contains the Name_Id for the

   --  generated file name.

   procedure Write_Binder_Info (Info : String);

   --  Writes the contents of the referenced string to the binder output file

   --  created by a previous call to Create_Binder_Output. Info represents a

   --  single line in the file, but does not contain any line termination

   --  characters. The implementation of Write_Binder_Info is responsible

   --  for adding necessary end of line and end of file control characters

   --  as required by the operating system.

   procedure Close_Binder_Output;

   --  Closes the file created by Create_Binder_Output, flushing any

   --  buffers etc. from writes by Write_Binder_Info.

   procedure Set_Current_File_Name_Index (To : Int);

   --  Set value of Current_File_Name_Index (in private part of Osint) to To

end Osint.B;
