---------------------------------------------------------------------- (0006863) geoffclare (manager) - 2024-08-15 15:33 https://austingroupbugs.net/view.php?id=1847#c6863 ---------------------------------------------------------------------- Interpretation response ------------------------ The standard states that <dlfcn.h> defines Dl_info_t and does not define Dl_info, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- There is existing application code that uses Dl_info_t and existing code that uses Dl_info. To enable both to be ported to a standard-conforming environment with minimal change, the standard should define both types. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- After page 238 line 8393 section <dlfcn.h>, add: <blockquote>The <b><dlfcn.h></b> header shall define the <b>Dl_info</b> type to be the same type as <b>Dl_info_t</b>.</blockquote> On page 238 line 8409 section <dlfcn.h>, change APPLICATION USAGE from "None" to: <blockquote>Although this standard requires <b>Dl_info</b> and <b>Dl_info_t</b> to be defined as synonyms for the same type, historically many systems only defined <b>Dl_info</b> and did not define <b>Dl_info_t</b>. Consequently, choosing to use <b>Dl_info</b> over <b>Dl_info_t</b> may provide better portability to non-conforming implementations (such as those which conform to earlier versions of this standard from before <i>dladdr</i>() was added but which also provide <i>dladdr</i>() as an extension).</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2024-08-02 01:15 philip-guentherNew Issue 2024-08-02 01:15 philip-guentherName => Philip Guenther 2024-08-02 01:15 philip-guentherOrganization => OpenBSD 2024-08-02 01:15 philip-guentherSection => dlfnc.h and dladdr() 2024-08-02 01:15 philip-guentherPage Number => 238 and 2024-08-02 01:15 philip-guentherLine Number => 8391 and 2024-08-05 14:41 geoffclare Note Added: 0006856 2024-08-11 01:46 philip-guentherNote Added: 0006859 2024-08-11 01:47 philip-guentherNote Added: 0006860 2024-08-15 15:33 geoffclare Note Added: 0006863 ======================================================================
