    Re: How to get capabilities of system libraries?

    My program needs TCB capability, but it also relies on some dlls without TCB capability like bafl.dll and charconv.dll.

    While I start to debug it on real device, I found it can't work. I'm sure it's not certficifate problem.

    Any information or advise is appreciated.

    Thanks in advance

    I think normally SDK DLLs have a capability of All-TCB.

    Yes, you're right.
    But for a TCB required program, I have to avoid call them.

    According to symbian rules, I dont think you can use other DLLs if your application have TCB cap.

    But TCB?! , if you are not working for Nokia, I dont know how you get your sis file signed.

    My company is nokia parterner. So I'm not afraid about it.

    Here's my solution, I dumped system dlls from phone and check the capabilities in the binary.
    For non-rom dll, its offset is 0x88; for rom dll its offset is 0x4c. You would get a dword like 0x0FFFFFE. The capabilities are associated with the low 20 bits.
    Accord to e32capabilities.h, I can get the information.
