Thanks.
@atr000 This does not work?
#if defined(__APPLE__)
// Mac OS X / Darwin features
#include <libkern/OSByteOrder.h>
#define bswap_16(x) OSSwapInt16(x)
#define bswap_32(x) OSSwapInt32(x)
#define bswap_64(x) OSSwapInt64(x)
#endif
How about something as simple as this?
#define bswap_16 __builtin_bswap16
#define bswap_32 __builtin_bswap32
#define bswap_64 __builtin_bswap64
