Line 20:
:: That would probably be a good Idea. With what's here, the main purpose gets rather lost in the haystack.--[[User:Rldrenth|Rldrenth]] 13:40, 17 January 2010 (UTC)
::: +1 --[[User:Paddy3118|Paddy3118]] 16:59, 17 January 2010 (UTC)
:: I would argue against replacing the example wholesale, but I wouldn't mind seeing an additional example using the glibc library. It becomes a comparison of "roll-your-own" versus using a library. ''Eventually'', changes the site's organization (and, likely, software) will make multiple side-by-side examples in the same language less clunky. --[[User:Short Circuit|Michael Mol]] 20:24, 17 January 2010 (UTC)
::: An example based on an existing library would be clearer to most readers. One could then put a link on that example to this one, and state that this one would provide some information about how the libraries are implemented for those with the diligence to wade through considerable code. Truth is, this example will not be useful to most readers, but it may provide some insight to a few of the curious. --[[User:Rldrenth|Rldrenth]] 22:32, 17 January 2010 (UTC)
:You'd be amazed at how many object systems have been implemented in C and other mostly procedural languages. OO is a useful enough design pattern that whole languages have been built around it, after all. In C, the implementer gets to choose ''how'' to implement it, instead of relying on the particular implementation built into the language. That's one reason we have Objective-C vs. C++. For example, the OO system built into the heart of Unix; what else is a device but a couple of classes (character, block) designed to be polymorphic on the open/close/read/write/ioctl interface, implemented as a couple big vtables? Most of the ad-hoc OO systems I've seen don't have general inheritance, relying instead on explicit delegation. --[[User:IanOsgood|IanOsgood]] 18:35, 17 January 2010 (UTC)
:: Is there a C OO library that is most popular that could be used for this task then? I too would prefer we used an existing library, but I would also prefer a library that was prominent within the C community and "general purpose". --[[User:Paddy3118|Paddy3118]] 06:02, 18 January 2010 (UTC)
::: It would be good to show off how to do it with glib (as noted above) and Xt (horrible, but still existing) as additional sections. If there are others, they can be added too; no reason why not! –[[User:Dkf|Donal Fellows]] 10:04, 18 January 2010 (UTC)
:::: +1. I'll go a step farther and point out that some C examples might be small enough to not require breaking out into a subpage, bringing more content into immediate view. --[[User:Short Circuit|Michael Mol]] 15:01, 18 January 2010 (UTC)
::::: I doubt if Xt would fall into that category, though. IIRC, its even more of a task to subclass than the example seen here. --[[User:Rldrenth|Rldrenth]] 16:01, 18 January 2010 (UTC)
