範例

// crt_byteswap.c
#include <stdlib.h>

int main()
{
   unsigned __int64 u64 = 0x0102030405060708;
   unsigned long ul = 0x01020304;

   printf("byteswap of %I64x = %I64x\n", u64, _byteswap_uint64(u64));
   printf("byteswap of %Ix = %Ix", ul, _byteswap_ulong(ul));
}
byteswap of 0102030405060708 = 0807060504030201
byteswap of 01020304 = 04030201
