GNU also has some compiler intrinsics to perform the same, so you can avoid the cost of the function call to OS services. http://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html see __builtin_bswap32 __builtin_bswap64 -----Original Message----- From: darwin-dev-bounces+nathanh=microsoft.com@lists.apple.com [mailto:darwin-dev-bounces+nathanh=microsoft.com@lists.apple.com] On Behalf Of Jean-Daniel Dupas Sent: Wednesday, April 21, 2010 6:02 AM To: Arnab Ganguly Cc: darwin-dev@lists.apple.com Dev Subject: Re: need help on porting from 32bit to 64bit. Swapping byte on OS X is a matter of taste. OSSwap API (libkern) NSSwap API (Foundation) CFSwap API (CoreFoundation) Core Endian API (CoreServices) and probably other hidden somewhere.

What about OSSwapBigToHostInt64 and OSSwapHostToBigInt64 both from #include <libkern/OSByteOrder.h> ?
