OptionArg
- class OptionArg
The OptionArg
enum values determine which type of extra argument the
options expect to find. If an option expects an extra argument, it can
be specified in several ways; with a short option: -x arg
, with a long
option: --name arg
or combined in a single argument: --name=arg
.
