Answer 1

One possible solution could be defining a format for the message that client send to server. For example you could define a protocol as follow:

[4 bytes length of your message][2 bytes for first player][2 bytes for second one] and in server side you should at first in rcv function get 4 bytes and extract the length of the arrived message and based on the receiving length(L) call again the rcv function with size L after that you should parse received messaged and extract the turn of each players.
