MSP430FR6989: How to watch a variable in a library file in CCS

Part Number: MSP430FR6989

I am trying to view the value of a variable that is used within a library function. For example, I am implementing the KISS FFT library on an MSP430. I call the kiss_fftr_alloc function, which allocates memory. It is failing to do so, so I want to check the memneeded variable to see if it is requiring more memory than I have available. memneeded exists only inside the function and is defined there. It appears nowhere in my main file. Because it is defined within the kiss_fftr_alloc function definition, I cannot set it as a global variable.  Is there a way for me to make it appear in the variables or expressions tabs, or to easily send the variable value to the console?
