Usage

libkcp has been designed as a Frame-Driven library, the main loop was supposed as:

GameInit()
NetworkInit()
While (!isGameOver) Do      // e.g:  A 30FPS Game
       LibKCP.Read()
       LibKCP.Write()
       LibKCP.Update()
       Game.Logic()
       Game.Render()
       Wait(33ms)   // clock
End

The Read/Write/Update functions of libkcp are guaranteed to be non-blocking.
Please read kcp_test.cpp fec_test.cpp for library usage.
