C getopt multiple value

Question

My argument is like this

./a.out -i file1 file2 file3

How can I utilize getopt() to get 3 (or more) input files? I\'m doing s

Answer 1

The solution by GoTTimw has proven very useful to me. However, I would like to mention one more idea, that has not been suggested here yet.

Pass arguments as one string in this way.

./a.out -i "file1 file2 file3"

Then you get one string as a single argument and you only need to split it by space.
