Compiler/IWR6843ISK: readUartCallbackFcn(hDataSerialPort, 0); Invalid

Tool/software: TI C/C++ Compiler

Hi, 

I tried to run below this Matlab code which I got from the other forum, but why readUartCallbackFcn(hDataSerialPort, 0); function invalid, I just I to know can I use this code for IWR6843 ES 1.0?
