-- This child package contains a routine to read and process Source_File_Name
-- pragmas from the gnat.adc file in the current directory. In order to use
-- the routines in package Fname.UF, it is required that Source_File_Name
-- pragmas be processed. There are two places where such processing takes
-- place:
-- The compiler front end (par-prag.adb), which is the general circuit
-- for processing all pragmas, including Source_File_Name.
-- The stand alone routine in this unit, which is convenient to use
-- from tools that do not want to include the compiler front end.
-- Note that this unit does depend on several of the compiler front-end
-- sources, including osint. If it is necessary to scan source file name
-- pragmas with less dependence on such sources, look at unit SFN_Scan.
package Fname.SF is
procedure Read_Source_File_Name_Pragmas;
-- This procedure is called to read the gnat.adc file and process any
-- Source_File_Name pragmas contained in this file. All other pragmas
-- are ignored. The result is appropriate calls to routines in the
-- package Fname.UF to register the pragmas so that subsequent calls
-- to Get_File_Name work correctly.
--
-- Note: The caller must have made an appropriate call to the
-- Osint.Initialize routine to initialize Osint before calling
-- this procedure.
--
-- If a syntax error is detected while scanning the gnat.adc file,
-- then the exception SFN_Scan.Syntax_Error_In_GNAT_ADC is raised
-- and SFN_Scan.Cursor contains the approximate index relative to
-- the start of the gnat.adc file of the error.
end Fname.SF;
