Hi, I was just wondering if I was able to change the return type of read_sysconfig to int to be able to return a value of how many devices I have read. I plan to use this to make sure I am not reading garbage when I use the array of device structures to print out its contents and when accessing the information within these structures. The parameters in the starting code for read_sysconfig also used argv[0] as a parameter but I feel as though the name of the program is not needed for this function. Can I also change this similarly or does the project have to stick to the template provided? Thank you
