| |
Hello everybody, The swapping method (in function void u32_swap() line no.. 14 to 16) in lib/sort.c can be improved by using the following code *(u32 *)b ^= *(u32 *)a ^= *(u32 *)b ^= *(u32 *)a instead of the code given. This code is not using third variable thus not consuming another memory. And I dont see any significance in using *int size* argument. so the function should be static void u32_swap(void *a, void *b) { *(u32 *)b ^= *(u32 *)a ^= *(u32 *)b ^= *(u32 *)a; }
