Or maybe OS X users need more help than other users. ;-)
The big question is: where would be the right spot for this information, if you want to keep even the documentation strictly OS-agnostic?
I'll add some of this information to the ddrescue manual (for example that raw character devices may have a defined size). But, given that most of the information is not specific to ddrescue but to accessing discs on OS X, I guess the right spot for it would be some OS X site or forum.
Then (if that method is generic enough) it could be inserted as an alternative to the O_DIRECT flag for platforms where that is unsupported.
If I ever discover a method for direct disc access more generic than O_DIRECT, I'll probably implement it instead of (not as an alternative to) O_DIRECT. I hate arbitrary differences among systems, and I work to reduce their number.
Something else: cat is quite a generic command, and still it manages to somehow select the optimal Copy Block Size for a raw character device on OS X. If the relevant code is not platform specific, it might contain some nice ideas.
If it is the cat from GNU coreutils, it probably includes platform specific code for every system under the sun through gnulib. But I'll look at the code just in case. :-)
