Compiler/LAUNCHXL-CC2650: Printing using UART

Part Number:LAUNCHXL-CC2650

Tool/software: TI C/C++ Compiler

Hello,

I want to use printf() function to print on the console, which I am not able to. So, I am referring http://dev.ti.com/tirex/#/?link=Development%20Tools%2FIntegrated%20Development%20Environments%2FCode%20Composer%20Studio%2FProjects%20and%20Build%2FDocuments%2FApplication%20Notes%2FTips%20for%20using%20printf, where I found this code snippet to use uart.

ret_val = add_device("uart", _SSA,
                     uart_open,
             uart_close,
             uart_read,
             uart_write,
             uart_lseek,
             uart_unlink,
             uart_rename);

fid = fopen("uart", "w");
freopen("uart:", "w", stdout);     // redirect stdout to uart
setvbuf(stdout, NULL, _IONBF, 0);  // turn off buffering for stdout
printf("Hello world!\r\n");

I am working on cc2650 Launchpad and using simple peripheral example. 

Can you please let me know where exactly I should use this code. The documentation is pretty vague, so I am not really sure how to use this.

Thanks ,

Rathna
