SFRA: Error in code

Part Number: SFRA

Hello experts

i am writing a new code for doing SFRA & following the steps given in C2000 Software Frequency Response Analyzer (SFRA) Library User’s Guide (Rev. A) (ti.com)

when calling  SFRA_F32_config, i am getting some error & not able to resolve it. i am not finished writing the code completely. but feel this erro not becuase of that. kindly help

the errors are 

#167: too few arguments in function call

#18: expected a ")"

the code is given below, kindly help

Regards 

Anoop
