It looks like this: <blockquote><pre>#if defined(__BIG_ENDIAN__) //All host=big implementations here #elif defined(__LITTLE_ENDIAN__) //All host=little implementations here #endif</pre></blockquote> I didn't see the #ifs at first. For posterity, here's what that section said when Blake wrote his comment: “The Const versions always swap; the others swap conditionally.”. Ah, good catch—I had misread the OSByteOrder.h header. It looks like this:

#if defined(__BIG_ENDIAN__)
//All host=big implementations here
#elif defined(__LITTLE_ENDIAN__)
//All host=little implementations here

I'm not sure what you mean- for example, OSSwapInt32 always swaps... "The Const versions always swap; the others swap conditionally."
