Compare that with a manual implementation of the same in C.

If you only care about Windows, for example, that's going to affect what

It might also be useful to know more about the context.  If this is for

why does it need to do tokenization and globbing?

This would be for work, so I am limited in what I can say about it, but
it has to be in C because it is would be a C callout from a GT.M mumps
process.  GT.M stores the command line tail (everything it doesn't need
to get a program running) in the special variable $ZCMDLINE which can
be passed to a callout.  I would like to parse that string as the
shell does a command line.  Basically, if it isn't a C library that
is commonly available through Linux package managers I probably can't
use it.  In the end this is a "nice to have" and I have a q&d approach
that I will probably use.

Since you mentioned Linux package managers, I presume this only needs to

Earlier I suggested using system() to pass the string to the shell.
That wouldn't work on Windows, but it should be ok for your
requirements.  There are good reasons not to want to do that, but "there
might not be a POSIX shell available" apparently isn't one of them.

I'd also suggest nailing down your exact requirements; "as the

Thank you.  system() would not work as I don't want to execute
anything, just parse into an argv-like array.

I appreciate the responses, but it looks like I will be staying with
my q&d approach for now.
