Re: [fpc-pascal] Is there a way to execute code after 'initialization' and before 'main', i. e. AddExitProc complement?

Maybe not exactly what you want but you could probably add the SortAndInitialize procedure to the initialization section of a new unit and add this unit as the last unit to your program. This use case is probably a good candidate for using the "section" modifier to specify initialization sequence. Unfortunately not available in the compiler for code sections AFAIK. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

'Initialization' sections are executed in poorly predictable order, so I
want to partially order them according to some form of explicit
prioritization and execute before control flow enters main block (so I
won't need to run all that initialization by hand, neither I would be able
to forget to do that).
If unit A uses unit B in the interface section then unit B's initialization
section is always run before A's. For the implementation section the same
holds true if there isn't a cycle otherwise it depends on the unit load
order.
Like:
unit UnitA;
...
procedure Init;
initialization
RegisterUnit('UnitA', @Init);
end;
unit UnitB;
...
procedure Init;
initialization
RegisterUnit('UnitB', @Init, {priority} +1);
end;
...
procedure SortAndInitialize;
...
Can I run SortAndInitialize before 'main' without additional user actions?
No, you can't.
