I've got in a similar situation again now;
I've got a luajit being controlled by another; and I'd like to
marshall CDATA objects across.
I essentially need a pointer to it, and the type...
The former is provided by lua_topointer; the latter I can get by doing
`tostring`, but of course that isn't very stable (eg, if there was a
metatype) or efficient.
Could you please add a function to the luajit api that returns the cdata type?
const char* luajit_cdatatype ( lua_State *L , int index )
returns NULL if the object is not of cdata type
