How to declare an option which doesn't allow any argument using getopts

Question

I'm trying to understand how we can configure options for a ksh script using getopts and I have found below details on declaring options using getopts:

Use : for options that require arguments.
Use # for options that require numeric arguments.
Use :? and #? for options that allow arguments but don't require them.

But is it possible to declare an option that doesn't allow any argument and add textual description about the option?

Answer 1

Different getopt()s do it differently. There are ones for different languages, even... which one?

Read The Fine Documentation! I'm sure you'll find assorted examples there, and as a bonus, faster than asking here and waiting for an answer.
