thank you bob for your reply, is there any other alternative than
sending Binary to NIF?
My string has an xml which I intent to parse in C NIF and give it back
to erlang program. I make ERL_NIF_TERMS in C function and give them
back to erlang, I would like to have the format as string only. Or do
u have suggestions for any other format for the kind of operation I am
