Is there a common open source C library for tokenizing and globbing
this into an argc/argv as a shell would do?  I've googled, but I get
too much C++ & other language stuff.

I also suppose that by "tokenizing" you don't mean something like

but a field separation as the Unix shell does using 'IFS'.

More or less, and homething that understands double and single quoting
so that a token can have white space inside.  Backslash handling
would be nice too so

'Who\'s a good boy?'

would work as one token.

I don't know of a C library but if I'd want to implement a function
that all POSIX shells do then I'd look into the shell packages...

For Kornshell (e.g. version 93u+m) I see these files in the package
 src/lib/libast/include/glob.h
 src/lib/libast/misc/glob.c
that obviously care about the globbing function. (I suspect you'll
need some more supporting files from the ksh package.)

Thanks, fixing up something out of shell components is probably more
than I want to take on here though.
