Finish off my C function to load a CSV file to an array of a structure

I don't have time to spend programming, so I want some help to finish off the function I started writing. I started to write a function struct record* loadcsv(char *filename) which reads from a CSV file of fixed format to an array of a structure. Its very simple C Stuff with fscanf's reading from the file into the array. Some of the Strings will be Hexadecimal strrings so need to be turned into uint32_t. It must be C and not CPP
