The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

No worries.

I had wondered if I might not get an answer with considerably wider scope than my example.
I just checked through zlib an cxImage for examples of its use. No luck with zlib and only limited examples of it in cxImage.

cxImage also claims its "tested with Visual C++ 6 / 2008, C++ Builder 3 / 6, MinGW on Windows, and with gcc 3.3.2 on Linux." (http://www.xdp.it/cximage.htm[^])Since it deals with image header structs, I figured it'd be a good place to go looking for #pragma pack

I found it, but only in the MSVC format (i.e #pragma pack(n) and #pragma pack() pairs )

All David's done is to wrap all of the structs needing byte alignment into a single pair of pack statements. From bitter experience, I know that bitmap handling can explode spectacularly when the struct packing isn't considered.

With that in mind, and if you've the time, I'd be 1/2 way tempted to try to build it with each platform you're interested in. Though surely, there must be an easier and less labour-intensive way to find out. Whether or not you'd have the answer sooner though, I'm not prepared to wager on. Wink | ;)
