不知道为什么client在二次read的时候，返回值会是-1，它应该是0才对。
谢谢。
./server&
./client username
>>hello
/*server program
run as ./server &
*/

I reassign the value of t
in while loop of client funtion
by t=int(*argv) every loop,
then it works.
seem t becomes 0 after each loop
why?
I use recv for "read"
Thank

actually, very simple.
You should not share t among different threads.
