-- GNAT was originally developed by the GNAT team at New York University. --
-- It is now maintained by Ada Core Technologies Inc (http://www.gnat.com). --
-- --
------------------------------------------------------------------------------
-- 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
procedure Record_Time_From_Last_Bind;
-- Trigger the computing of the time from the last bind of the same
-- program.
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.
function Time_From_Last_Bind return Nat;
-- This function give an approximate number of minute from the last bind.
-- It bases its computation on file stamp and therefore does gibe not
-- any meaningful result before the new output binder file is written.
-- So it returns Nat'last if:
--
-- - it is the first bind of this specific program
-- - Record_Time_From_Last_Bind was not Called first
-- - Close_Binder_Output was not called first
--
-- otherwise it returns the number of minutes from the last bind. The
-- computation does not try to be completely accurate and in particular
-- does not take leap years into account.
-------------------
-- 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.
end Osint.B;
