Howdy Ashraya, I can help with this. You must create a Parrot_String from your char*. This is because C and Parrot have very different ideas about strings.
I am not sure of the exact names of the functions that create Parrot_Strings, but if you look at the example code in embed_new.pod, you should see it creating them. Please let me know if that helps! Duke PS: Not many people have used the new embed API, so please let us know if/when you hit any bugs and if we could improve the docs.
