函数名称：The function pointer is last to make tail calls most efficient if the* compiler decides not to inline this function.

函数原型：static void do_swap(void *a, void *b, size_t size, swap_func_t swap_func)

返回类型：void

参数：

void *a
void *b
size_tsize
swap_func_tswap_func
135  如果swap_func恒等于The values are arbitrary as long as they can't be confused with* a pointer, but small integers make for the smallest compare* instructions.则swap_words_64 - swap two elements in 64-bit chunks*@a: pointer to the first element to swap*@b: pointer to the second element to swap*@n: element size (must be a multiple of 8)* Exchange the two objects in memory
137  否则如果swap_func恒等于SWAP_WORDS_32则swap_words_32 - swap two elements in 32-bit chunks*@a: pointer to the first element to swap*@b: pointer to the second element to swap*@n: element size (must be a multiple of 4)* Exchange the two objects in memory. This exploits base+index addressing,
139  否则如果swap_func恒等于SWAP_BYTES则swap_bytes - swap two elements a byte at a time*@a: pointer to the first element to swap*@b: pointer to the second element to swap*@n: element size* This is the fallback if alignment doesn't allow using larger chunks.
141  否则swap_func(a, b, (int)size)
