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.

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
