Full Discussion: Combine GetOpt And Variadic Function In C
Top Forums Programming Combine GetOpt And Variadic Function In C Post 303031155 by Azrael on Friday 22nd of February 2019 08:14:16 AM

I guess I didn't explain things well. I assumed using a variadic function would be the only way to get optional and required parameters. I tried to implement the code from Corona688 in my own, but could not get it to work. I did more searching and came back to example 2 on this page I had been to before:

CS 417 Documents

From that example I was able to see the flags in the switch case that could make arguments required.
Code:
$ ./basic -dp -s "more stuff" blah
./basic: missing -f option
usage: ./basic [-dmp] -f fname [-s sname] name [name ...]

Thank you for the response.
