[c api] Finding coroutine "parent"

[matias.guijarro@...]

Hello,

I wonder if there is a way to determine the "parent" lua_State
of a coroutine, given its own lua_State. In other words, I am
trying to find the lua_State a given coroutine has been created
from.

Is it possible ?
For the moment I am stuck.

Thanks in advance,
Matias.
