The question is
"how can i write operating system dependent stuff in an
operation independent manner"
and the answer is
"by isolating O/S dependent stuff in a package"
package Unix.Line_Terminators is
Line_Terminator : constant String := Ascii.LF & "";
end;
with Unix.Line_Terminators;
package OS.Line_Terminators is
Line_Terminator : String renames Unix.Line_Terminators.Line_Terminator;
end;
and then get your configuration system to choose the appropriate with
(maybe even use a preprocessor! to select a with statement).
Thinking about it, the preprocessor selection of a with statement
would seem to be a fairly benign use of preprocessors. Can anyone see
any great harm in this scheme?
