-- This package contains the function used to read SCO information from an ALI
-- file and populate the tables defined in package SCOs with the result.
-- These subprograms provide access to the ALI file. Locating, opening and
-- providing access to the ALI file is the callers' responsibility.
with function Getc return Character is <>;
-- Get next character, positioning the ALI file ready to read the following
-- character (equivalent to calling Nextc, then Skipc). If the end of file
-- is encountered, the value Types.EOF is returned.
with function Nextc return Character is <>;
-- Look at the next character, and return it, leaving the position of the
-- file unchanged, so that a subsequent call to Getc or Nextc will return
-- this same character. If the file is positioned at the end of file, then
-- Types.EOF is returned.
with procedure Skipc is <>;
-- Skip past the current character (which typically was read with Nextc),
-- and position to the next character, which will be returned by the next
-- call to Getc or Nextc.
procedure Get_SCOs;
-- Load SCO information from ALI file text format into internal SCO tables
-- (SCOs.SCO_Table and SCOs.SCO_Unit_Table). On entry the input file is
-- positioned to the initial 'C' of the first SCO line in the ALI file.
-- On return, the file is positioned either to the end of file, or to the
-- first character of the line following the SCO information (which will
-- never start with a 'C').
-- If a format error is detected in the input, then an exception is raised
-- (Ada.IO_Exceptions.Data_Error), with the file positioned to the error.
