Thread Subject: Passing C struct out to Matlab space

I have a need to see the content of a struct defined in a C-mex
program. I know there is a Matlab struct and if I really want, I can
copy the members of the C struct to Matlab struct but I really want to
avoid that. I also tried to simply set plhs[0] to the pointer to the
struct and it didn't work. It there a quick and dirty way that allows
one to see what's in a C struct in Matlab space?

There's no way to do what you want AFAIK. Matlab and C structs are
completely different, I remember reading someone's post here on a
similar topic that a Matlab structure would be more similar to a hash
table than a C structure. So you will have to copy over each member
from the C structure to the Matlab structure.

Thanks, I think this is a little deeper than I want to dig into at
this point. For now, I just copy the members to an array and pass the
array out.
