No, you're thinking about this backwards. You can't mix the ffi and the
classical Lua C api. So trying to get the Lua callstack from a C function
called via the ffi is a bad idea, it shouldn't even be aware of Lua.
Better is to return an error code from your function and construct the
error message with callstack in the calling Lua code.
Cheers,
Dan
