Why is this function in the library and in the documentation if it's not supported?  The documentation says it's not 
supported, but when porting code to Neutrino, you wouldn't expect an unsupported function to compile.  Also, the 
documentation says it should set errno, but it doesn't, it only returns -1.

Is there an alternative function I can use to do word expansions?

Thanks

Re: wordexp

My guess is: To be at least partially POSIX-compliant... 

One might argue that a minimal implementation stating that it won't do anything is still a 'valid' implementation -- 
although from a practical point of view, I'd readily agree with you.

You're right about the docs: Not  errno  is set, but the error code is returned (the -1 you're seeing is ,in fact' 
WRDE_NOSYS).

RE: wordexp

I'll create a PR to update the docs for wordexp().
