Format lib OMF-166

Valery Jan

Hi!
I paid attention to the new update of compiler for С166. OMF-166 library file format (*.lib) has been changed. Where could I find materials about this new format? Or with whom could the new

    What specifically do you need to know?

    For instance, there are old format file fragments of rtx166*.lib library. This file coincides with description from http://www.keil.com/support/docs/93.htm. The other one is a file than I'm interested in.

    Also that in occasion of a format ?

    Again, What specifically do you need to know?

    Unless you're building your own library tools, surely this should be just a private matter for the Librarian?

    If you are developing add-on tools, I imagine you would be better off negotiating directly with Keil - rather than posting in a public forum...?

    Thank you for the information.
    I create GUI utility (analog of lib166.exe) for operanion with 166 libraries.
    While testing program with remote beta-tester а library was received with new record types. Ther is no description of them in the manual.
    I put examples of some:

    etc.


    Where and how can I get description of new (in comparison with the one at http://www.keil.com/support/docs/93.htm
    (OMF-166 object module format for object modules)) new RECORD types.

  • 0 in reply to Valery Jan

    There are a number of proprietary record types in all object module formats. They "secret" records contain dependency information, source browser details, and so on. This information is not available to the general public.

    The record length and a checksum are encoded into each record so you can safely verify that a record is valid and you can skip over the ones you don't know how to interpret.
