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

Note that glibc's nonconformant argument permutation extension will break any attempt to use multiple arguments to -i in this manner. And on non-GNU systems, the "second argument to -i" will be interpreted as the first non-option argument, halting any further option parsing. With these issues in mind, I would drop getopt and write your own command line parser if you want to use this syntax, since it's not a syntax supported by getopt.
