Yes, but that's no work for you.

Wildcard expansion is a feature of the shell, not the program that's
invoked.

That is, if you run

prog *.c

the shell expands '*.c' to all the files that end in '.c' and your
program's argv will be e.g. ['prog', 'file1.c', 'foo.c', 'bar.c'].

Supporting '--' to signify the end of command-line options is provided
to you by getopt(3).
