Q&A
===
* tcp 怎麼決定 send 出去的封包要分成幾份,最大多少?
* malloc() v.s calloc()
  [name=Solomon] 
  * The calloc() function allocates space for number objects, each size bytes in length. The result is identical to calling malloc() with an argument of number * size.with the exception that the allocated memory       is explicitly initialized to zero bytes.
 memset(void *dest, int c, size_t len);
 
Assign works
