I'm using getopt_long() to process a command line.
So after a typical call I might have:
argv == {"./efind", "-D", "-x", "one", "two", "three", "four"}
optind == 3
What I'd like to do (without copying or mallocing and without using a
VLA)
is to get a pointer to a slice of argv, specifically,
{"one", "two", "three", "four"}.
In Python terms argv[optind:argc].
Is this possible in C?
Yes.
const char * argv_slice[argc - optind] = &argv[optind];
